Relationship Between Quality of Life and Energy Usage
by Reza NadimiThis book utilizes statistical techniques to define a quality of life (QoL) indicator combining the three dimensions of economy, health, and education. In turn, it uses modeling to assess the impact of energy consumption on 112 countries’ QoL. What sets the proposed model apart from previous research is its ability to distinguish between pre-developing, developing, and developed countries. One important aspect of this distinction is their different global energy policies and their priorities with regard to achieving sustainable energy consumption. Accordingly, the book also discusses eco-sufficiency, eco-efficiency, and energy poverty reduction for the three different types of countries. In turn, the book provides general information on how to reconcile sustainable energy consumption with QoL and economic development. Optimization programming technique and simulation are applied to measure potential energy saving in each country, without sacrificing economic progress, and while maintaining QoL. Given its scope, the book is highly recommended to the following audiences: (1) readers seeking a state-of-the-art quantitative work on energy systems and QoL; (2) manufacturers and developers of renewable energy technologies who consider renewables as an option for mitigating energy poverty; and (3) international institutions such as the United Nations seeking a sustainable global energy strategy.
Relativer Quantenquark
by Holm Gero HümmlerDieses Buch räumt mit der Vorstellung auf, dass esoterische und alternativmedizinische Konzepte mit der Relativitätstheorie und Quantenphysik zu begründen wären: „Die Quantenheilung basiert auf den Erkenntnissen der Quantenphysik“, heißt es in Internetseiten, Büchern und Broschüren zahlreicher Alternativmediziner. Hypnotiseure und Reiki-Meister folgern aus E = mc², dass Materie aus der Energie der Gedanken entsteht. „Alles ist vorstellbar“, folgt in einem Buch über Schamanismus aus der Quantenmechanik.Um zwischen Grenzgebieten der Physik und Quantenunsinn unterscheiden zu können, nimmt der Autor die Leser mit auf eine Reise durch die Grundlagen der Quantenphysik und Relativitätstheorie und beschreibt, welche Hürden diese Theorien nehmen mussten, um als wissenschaftlich anerkannt zu werden. "Quarkstückchen" zeigen reale Beispiele für Kurioses und Unwissenschaftliches, das den Anschein erweckt, sich auf Quantenphysik und Relativitätstheorie zu stützen.Wer sich auf Einstein, Heisenberg oder Schrödinger beruft, beansprucht wissenschaftliche Seriosität und schreckt unangenehme Fragen ab. Was steckt aber wirklich hinter den Theorien der modernen Physik? Holm Hümmler erläutert die wichtigsten Konzepte und zeigt auf, wo Wissenschaft nur falsch verstanden und wo sie in Scheinargumenten missbraucht wird.
Relativistic Celestial Mechanics of the Solar System
by Sergei Kopeikin Michael Efroimsky George KaplanThis authoritative book presents the theoretical development of gravitational physics as it applies to the dynamics of celestial bodies and the analysis of precise astronomical observations. In so doing, it fills the need for a textbook that teaches modern dynamical astronomy with a strong emphasis on the relativistic aspects of the subject produced by the curved geometry of four-dimensional spacetime. The first three chapters review the fundamental principles of celestial mechanics and of special and general relativity. This background material forms the basis for understanding relativistic reference frames, the celestial mechanics of N-body systems, and high-precision astrometry, navigation, and geodesy, which are then treated in the following five chapters. The final chapter provides an overview of the new field of applied relativity, based on recent recommendations from the International Astronomical Union. The book is suitable for teaching advanced undergraduate honors programs and graduate courses, while equally serving as a reference for professional research scientists working in relativity and dynamical astronomy. The authors bring their extensive theoretical and practical experience to the subject. Sergei Kopeikin is a professor at the University of Missouri, while Michael Efroimsky and George Kaplan work at the United States Naval Observatory, one of the world?s premier institutions for expertise in astrometry, celestial mechanics, and timekeeping.
Relativistic Cosmology
by George F. R. Ellis Roy Maartens Malcolm A. H. MaccallumCosmology has been transformed by dramatic progress in high-precision observations and theoretical modelling. This book surveys key developments and open issues for graduate students and researchers. Using a relativistic geometric approach, it focuses on the general concepts and relations that underpin the standard model of the Universe. Part I covers foundations of relativistic cosmology whilst Part II develops the dynamical and observational relations for all models of the Universe based on general relativity. Part III focuses on the standard model of cosmology, including inflation, dark matter, dark energy, perturbation theory, the cosmic microwave background, structure formation and gravitational lensing. It also examines modified gravity and inhomogeneity as possible alternatives to dark energy. Anisotropic and inhomogeneous models are described in Part IV, and Part V reviews deeper issues, such as quantum cosmology, the start of the universe and the multiverse proposal.

Relativistic Dissipative Hydrodynamic Description of the Quark-Gluon Plasma
by Akihiko MonnaiThis thesis presents theoretical and numerical studies on phenomenological description of the quark-gluon plasma (QGP), a many-body system of elementary particles. The author formulates a causal theory of hydrodynamics for systems with net charges from the law of increasing entropy and a momentum expansion method. The derived equation results can be applied not only to collider physics, but also to the early universe and ultra-cold atoms. The author also develops novel off-equilibrium hydrodynamic models for the longitudinal expansion of the QGP on the basis of these equations. Numerical estimations show that convection and entropy production during the hydrodynamic evolution are key to explaining excessive charged particle production, recently observed at the Large Hadron Collider. Furthermore, the analyses at finite baryon density indicate that the energy available for QGP production is larger than the amount conventionally assumed.
Relativistic Dynamics of a Charged Sphere: Updating the Lorentz-Abraham Model
by Arthur D. YaghjianIn addition to expanding and clarifying a number of sections of the first edition, it generalizes the analysis that eliminates the noncausal pre-acceleration so that it applies to removing any pre-deceleration as well. It also introduces a robust power series solution to the equation of motion that produces an extremely accurate solution to problems such as the motion of electrons in uniform magnetic fields.
Relativistic Effects in Interatomic Ionization Processes and Formation of Antimatter Ions in Interatomic Attachment Reactions
by Andreas JacobInteratomic energy transfer phenomena caused by efficient long-range electron correlations are among the most studied processes in atomic physics today. They can provide important insights into the interaction dynamics of single atomic species with their environment in more complex systems. Part I of this book covers fundamental aspects of two interatomic ionization processes relying on the efficient transfer of electronic energy via long-range electron correlations between two spatially well-separated atomic species with an emphasis on the influence of relativistic effects on ionization. Part II of this book deals with an application of interatomic energy transfer in antimatter physics, investigating attachment mechanisms for the production of substantial amounts of the positive ion of antihydrogen in view of experiments on the free-fall of antihydrogen currently planned at CERN.
Relativistic Electron Mirrors
by Daniel KieferA dense sheet of electrons accelerated to close to the speed of light can act as a tuneable mirror that can generate bright bursts of laser-like radiation in the short wavelength range simply via the reflection of a counter-propagating laser pulse. This thesis investigates the generation of such a relativistic electron mirror structure in a series of experiments accompanied by computer simulations. It is shown that such relativistic mirror can indeed be created from the interaction of a high-intensity laser pulse with a nanometer-scale, ultrathin foil. The reported work gives a intriguing insight into the complex dynamics of high-intensity laser-nanofoil interactions and constitutes a major step towards the development of a relativistic mirror, which could potentially generate bright burst of X-rays on a micro-scale.
Relativistic Geodesy: Foundations and Applications (Fundamental Theories of Physics #196)
by Dirk Puetzfeld Claus LämmerzahlDue to steadily improving experimental accuracy, relativistic concepts – based on Einstein’s theory of Special and General Relativity – are playing an increasingly important role in modern geodesy. This book offers an introduction to the emerging field of relativistic geodesy, and covers topics ranging from the description of clocks and test bodies, to time and frequency measurements, to current and future observations. Emphasis is placed on geodetically relevant definitions and fundamental methods in the context of Einstein’s theory (e.g. the role of observers, use of clocks, definition of reference systems and the geoid, use of relativistic approximation schemes). Further, the applications discussed range from chronometric and gradiometric determinations of the gravitational field, to the latest (satellite) experiments. The impact of choices made at a fundamental theoretical level on the interpretation of measurements and the planning of future experiments is also highlighted. Providing an up-to-the-minute status report on the respective topics discussed, the book will not only benefit experts, but will also serve as a guide for students with a background in either geodesy or gravitational physics who are interested in entering and exploring this emerging field.

Relativistic Kinetic Theory
by Gregory V. Vereshchagin Alexey G. AksenovRelativistic kinetic theory has widespread application in astrophysics and cosmology. The interest has grown in recent years as experimentalists are now able to make reliable measurements on physical systems where relativistic effects are no longer negligible. This ambitious monograph is divided into three parts. It presents the basic ideas and concepts of this theory, equations and methods, including derivation of kinetic equations from the relativistic BBGKY hierarchy and discussion of the relation between kinetic and hydrodynamic levels of description. The second part introduces elements of computational physics with special emphasis on numerical integration of Boltzmann equations and related approaches, as well as multi-component hydrodynamics. The third part presents an overview of applications ranging from covariant theory of plasma response, thermalization of relativistic plasma, comptonization in static and moving media to kinetics of self-gravitating systems, cosmological structure formation and neutrino emission during the gravitational collapse.
Relativistic Magnetrons
by Igor VintizenkoThe first experiments with relativistic magnetrons (PM), resulted in notable results, in the USA – Massachusetts Institute of Technology and the USSR - Institute of Applied Physics. Academy of Sciences of the USSR (Gorky), and the Nuclear Physics Research Institute at the Tomsk State University, hundreds of megawatts to several gigawatts with an efficiency of 10-30% were obtained. Relativistic high-frequency electronics has now become one of the fastest growing areas of scientific research. This reference is devoted to theoretical and experimental studies of relativistic magnetrons and is written by a leading expert who worked directly on these systems.
Relativistic Many-Body Theory
by Ingvar LindgrenRelativistic Many-Body Theory treats — for the first time — the combination of relativistic atomic many-body theory with quantum-electrodynamics (QED) in a unified manner. This book can be regarded as a continuation of the book by Lindgren and Morrison, Atomic Many-Body Theory (Springer 1986), which deals with the non-relativistic theory of many-electron systems, describing several means of treating the electron correlation to essentially all orders of perturbation theory. The treatment of the present book is based upon quantum-field theory, and demonstrates that when the procedure is carried to all orders of perturbation theory, two-particle systems are fully compatible with the relativistically covariant Bethe-Salpeter equation. This procedure can be applied to arbitrary open-shell systems, in analogy with the standard many-body theory, and it is also applicable to systems with more than two particles. Presently existing theoretical procedures for treating atomic systems are, in several cases, insufficient to explain the accurate experimental data recently obtained, particularly for highly charged ions. This shortcoming is expected to be due to omission of combined QED-correlational effects, included in the new unified procedure.<P><P> All methods treated in Relativistic Many-Body Theory are illustrated with numerical examples. The main text is divided into three parts.<P><P> In Part I, the standard time-independent and time-dependent perturbation procedures are reviewed.<P> Part II describes three methods for QED calculations, a) the standard S-matrix formulation, b) the Two-times Green’s-function method, developed by the St Petersburg Atomic Theory group, and c) the Covariant-evolution-operator (CEO) method, recently developed by the Gothenburg Atomic Theory group.<P> In Part III, the CEO method is combined with electron correlation to arbitrary order to a unified MBPT-QED procedure. In this procedure the electron correlation can be included to high order, and therefore this procedure is expected to lead to faster convergence than treating the BS equation order by order.<P> Ingvar Lindgren is also the author of the highly-cited "Atomic Many-Body Theory" book published by Springer.
Relativistic Many-Body Theory, 2nd Edition
by Ingvar LindgrenThis revised second edition of the author’s classic text offers readers a comprehensively updated review of relativistic atomic many-body theory, covering the many developments in the field since the publication of the original title. In particular, a new final section extends the scope to cover the evaluation of QED effects for dynamical processes.<P><P> The treatment of the book is based upon quantum-field theory, and demonstrates that when the procedure is carried to all orders of perturbation theory, two-particle systems are fully compatible with the relativistically covariant Bethe-Salpeter equation.

In Part I, the standard time-independent and time-dependent perturbation procedures are reviewed. This includes a new section at the end of chapter 2 concerning the so-called ”Fock-space procedure” or ”Coulomb-only procedure” for relativistic-QED calculations. This is a procedure on an intermediate level, frequently used in recent time by chemists on molecular systems, where a full QED treatment is out of question. Part II describes three methods for QED calculations, a) the standard S-matrix formulation, b) the Two-times Green’s-function method, developed by the St Petersburg Atomic Theory group, and c) the Covariant-evolution operator (CEO) method, recently developed by the Gothenburg Atomic Theory group. In Part III, the CEO method is combined with electron correlation to arbitrary order to a unified MBPT-QED procedure. The new Part IV includes two new chapters dealing with dynamical properties and how QED effects can be evaluated for such processes. This part is much needed as there has been an increasing interest in the study of QED effects for such processes.<P> All methods treated in the book are illustrated with numerical examples, making it a text suitable for advanced students new to the field and a useful reference for established researchers.
Relativistic Methods for Chemists
by Yasuyuki Ishikawa Maria Barysz"Relativistic Methods for Chemists", written by a highly qualified team of authors, is targeted at both experimentalists and theoreticians interested in the area of relativistic effects in atomic and molecular systems and processes and in their consequences for the interpretation of the heavy element's chemistry. The theoretical part of the book focuses on the relativistic methods for molecular calculations discussing relativistic two-component theory, density functional theory, pseudopotentials and correlations. The experimentally oriented chapters describe the use of relativistic methods in different applications focusing on the design of new materials based on heavy element compounds, the role of the spin-orbit coupling in photochemistry and photobiology, and chirality and its relations to relativistic description of matter and radiation. This book is written at an intermediate level in order to appeal to a broader audience than just experts working in the field of relativistic theory.
Relativistic Nonlinear Electrodynamics
by Hamlet K. AvetissianThis revised edition of the author's classic 2006 text offers a comprehensively updated review of the field of relativistic nonlinear electrodynamics. It explores the interaction of strong and super-strong electromagnetic/laser radiation with the electromagnetic quantum vacuum and diverse types of matter - including free charged particles and antiparticles, acceleration beams, plasma and plasmous media. The appearance of laser sources of relativistic and ultra-relativistic intensities over the last decade has stimulated investigation of a large class of processes under such super-strong radiation fields. Revisions for this second edition reflect these developments and the book includes new chapters on Bremsstrahlung and nonlinear absorption of superintense radiation in plasmas, the nonlinear interaction of relativistic atoms with intense laser radiation, nonlinear interaction of strong laser radiation with Graphene, and relativistic nonlinear phenomena in solid-plasma targets under supershort laser pulses of ultrarelativistic intensities. The only book devoted to the subject of relativistic nonlinear electrodynamics, this second edition will be a valuable resource for graduate students and researchers involved in any aspect of the field, including those working with intense x-ray - gamma-ray lasers, the new generation of small size laser-plasma accelerators of superhigh energies and high-brightness particle beams.
Relativistic Quantum Chemistry
by Markus Reiher Alexander WolfEinstein proposed his theory of special relativity in 1905. For a long time it was believed that this theory has no significant impact on chemistry. This view changed in the 1970s when it was realized that (nonrelativistic) Schrödinger quantum mechanics yields results on molecular properties that depart significantly from experimental results. Especially when heavy elements are involved, these quantitative deviations can be so large that qualitative chemical reasoning and understanding is affected. For this to grasp the appropriate many-electron theory has rapidly evolved. Nowadays relativistic approaches are routinely implemented and applied in standard quantum chemical software packages. As it is essential for chemists and physicists to understand relativistic effects in molecules, the first edition of 'Relativistic Quantum Chemistry - The fundamental Theory of Molecular Science' had set out to provide a concise, comprehensive, and complete presentation of this theory.The second edition of Relativistic Quantum Chemistry: The Fundamental Theory of Molecular Science expands on some of the latest developments in this fascinating field. The text retains its clear and consistent style, allowing for a readily accessible overview of the complex topic. It is also self-contained, building on the fundamental equations and providing the mathematical background necessary. While some parts of the text have been restructured for the sake of clarity a significant amount of new content has also been added. This includes, for example, an in-depth discussion of the Brown-Ravenhall disease, of spin in current-density functional theory, and of exact two-component methods and its local variants.A strength of the first edition of this textbook was its list of almost 1000 references to the original research literature, which has made it a valuable reference also for experts in the field. In the second edition, more than 100 additional key references have been added - most of them considering the recent developments in the field.Thus, the book is a must-have for everyone entering the field, as well as for experienced researchers searching for a consistent review.
Relativistic Quantum Invariance (Lecture Notes in Physics #1012)
by Chueng-Ryong JiThis book describes the invariant nature of the relativistic quantum field theories utilizing the idea of interpolating the instant form dynamics and the light-front dynamics. While the light-front dynamics (LFD) based on the light-front time was proposed by Dirac in 1949, there has not yet been a salient review on the connection between the LFD and the instant form dynamics (IFD) based on the ordinary time. By reviewing the connection between LFD and IFD using the idea of interpolating the two different forms of the relativistic dynamics, one can learn the distinguished features of each form and how one may utilize those distinguished features in solving the complicated relativistic quantum field theoretic problems more effectively. With the ongoing 12-GeV Jefferson Lab experiments, the internal structures of the nucleon and nuclei are vigorously investigated in particular using the physical observables defined in the LFD rather than in the IFD. This book offers a clear demonstration on why and how the LFD is more advantageous than the IFD for the study of hadron physics, illustrating the differences and similarities between these two distinguished forms of the dynamics. It aims at presenting the basic first-hand knowledge of the relativistic quantum field theories, describing why and how the different forms of dynamics (e.g., IFD and LFD) can emerge in them, connecting the IFD and the LFD using the idea of the interpolation, and demonstrating explicit examples of the interpolation in quantum electrodynamics and other field theories. While the level of presentation is planned mainly for the advanced undergraduate students and the beginning graduate students, the topics of the interpolation between the IFD and the LFD are innovative enough for even the experts in the field to appreciate its usefulness.
Relativistic Quantum Mechanics
by Lawrence P. HorwitzThis book describes a relativistic quantum theory developed by the author starting from the E. C. G. Stueckelberg approach proposed in the early 40s. In this framework a universal invariant evolution parameter (corresponding to the time originally postulated by Newton) is introduced to describe dynamical evolution. This theory is able to provide solutions for some of the fundamental problems encountered in early attempts to construct a relativistic quantum theory. A relativistically covariant construction is given for which particle spins and angular momenta can be combined through the usual rotation group Clebsch-Gordan coefficients. Solutions are defined for both the classical and quantum two body bound state and scattering problems. The recently developed quantum Lax-Phillips theory of semi group evolution of resonant states is described. The experiment of Lindner and coworkers on interference in time is discussed showing how the property of coherence in time provides a simple understanding of the results. The full gauge invariance of the Stueckelberg-Schroedinger equation results in a 5D generalization of the usual gauge theories. A description of this structure and some of its consequences for both Abelian and non-Abelian fields are discussed. A review of the basic foundations of relativistic classical and quantum statistical mechanics is also given. The Bekenstein-Sanders construction for imbedding Milgrom's theory of modified spacetime structure into general relativity as an alternative to dark matter is also studied.

Relativistic Quantum Mechanics: An Introduction to Relativistic Quantum Fields
by Luciano Maiani Omar BenharWritten by two of the most prominent leaders in particle physics, Relativistic Quantum Mechanics: An Introduction to Relativistic Quantum Fields provides a classroom-tested introduction to the formal and conceptual foundations of quantum field theory. Designed for advanced undergraduate- and graduate-level physics students, the text only requires previous courses in classical mechanics, relativity, and quantum mechanics.The introductory chapters of the book summarise the theory of special relativity and its application to the classical description of the motion of a free particle and a field. The authors then explain the quantum formulation of field theory through the simple example of a scalar field described by the Klein–Gordon equation as well as its extension to the case of spin ½ particles described by the Dirac equation. They also present the elements necessary for constructing the foundational theories of the standard model of electroweak interactions, namely quantum electrodynamics and the Fermi theory of neutron beta decay. Many applications to quantum electrodynamics and weak interaction processes are thoroughly analysed. The book also explores the timely topic of neutrino oscillations.Logically progressing from the fundamentals to recent discoveries, this textbook provides students with the essential foundation to study more advanced theoretical physics and elementary particle physics. It will help them understand the theory of electroweak interactions and gauge theories.View the second and third books in this collection: Electroweak Interactions and An Introduction to Gauge Theories.Key Features of the new edition:Besides a general revision of text and formulae, three new chapters have been added.· Chapter 17 introduces and discusses double beta decay processes with and without neutrino emission, the latter being the only process able to determine the Dirac or Majorana nature of the neutrino (discussed in Chapter 13). A discussion of the limits to the Majorana neutrino mass obtained recently in several underground laboratories is included.· Chapter 18 illustrates the calculation of the mass spectrum of “quarkonia” (mesons composed by a pair of heavy, charm or beauty quarks), in analogy with the positronium spectrum discussed in Chapter 12. This calculation has put into evidence the existence of “unexpected” states and has led to the new field of “exotic hadrons”, presently under active theoretical and experimental scrutiny.· Chapter 19 illustrates the Born-Oppenheimer approximation, extensively used in the computation of simple molecules, and its application to the physics of exotic hadrons containing a pair of heavy quarks, with application to the recently observed doubly charmed baryons.This eBook was published Open Access with funding support from the Sponsoring Consortium for Open Access Publishing in Particle Physics (SCOAP3).A PDF version of this book is available for free in Open Access at www.taylorfrancis.com.

Relativistic Quantum Physics
by Tommy OhlssonQuantum physics and special relativity theory were two of the greatest breakthroughs in physics during the twentieth century and contributed to paradigm shifts in physics. This book combines these two discoveries to provide a complete description of the fundamentals of relativistic quantum physics, guiding the reader effortlessly from relativistic quantum mechanics to basic quantum field theory. The book gives a thorough and detailed treatment of the subject, beginning with the classification of particles, the Klein-Gordon equation and the Dirac equation. It then moves on to the canonical quantization procedure of the Klein-Gordon, Dirac and electromagnetic fields. Classical Yang-Mills theory, the LSZ formalism, perturbation theory, elementary processes in QED are introduced, and regularization, renormalization and radiative corrections are explored. With exercises scattered through the text and problems at the end of most chapters, the book is ideal for advanced undergraduate and graduate students in theoretical physics.
Relativistic and Non-Relativistic Quantum Mechanics: Both at Once (Undergraduate Lecture Notes in Physics)
by Abhishek Singh Luis Grave de Peralta Maricela Fernández Lozada Hira Farooq Gage Eichman Gabrielle PrimeCurrently, relativistic quantum mechanics is considered an advanced topic only accessible to students who have already received considerable training in non-relativistic quantum mechanics. However, the authors believe that they have found an excellent pedagogic approach for simultaneously introducing both topics. This book is considered an Introductory Quantum Mechanics textbook that presents relativistic quantum mechanics to interested learners with no previous knowledge of it. The authors avoid utilization of the well-known Lorentz invariant equations. Additionally, they only refer to the Klein-Gordon and Dirac equations to justify the use of the Poveda-Poirier-Grave de Peralta (PPGP) equations, upon which this book is solely based (while sporadically referring to well-known results obtained using the Klein-Gordon and Dirac equations to avoid unnecessary complications in an introductory book). There also exist two complementary Schrödinger-like and Pauli-like PPGP equations, the solutions of which are identical to the respective solutions of the Klein-Gordon and Dirac equations associated with negative kinetic energies. These equations’ relation to the existence of antiparticles is discussed. The intended readership is undergraduate physics, chemistry, and engineering students with no previous knowledge of quantum mechanics, as well as graduate students and professionals interested in the subject.
Relativistically Intense Laser–Microplasma Interactions (Springer Theses)
by Tobias OstermayrThis dissertation covers several important aspects of relativistically intense laser–microplasma interactions and some potential applications. A Paul-trap based target system was developed to provide fully isolated, well defined and well positioned micro-sphere-targets for experiments with focused peta-watt laser pulses. The laser interaction turned such targets into microplasmas, emitting proton beams with kinetic energies exceeding 10 MeV. The proton beam kinetic energy spectrum and spatial distribution were tuned by variation of the acceleration mechanism, reaching from broadly distributed spectra in relatively cold plasma expansions to spectra with relative energy spread as small as 20% in spherical multi-species Coulomb explosions and in directed acceleration processes. Numerical simulations and analytical calculations support these experimental findings and show how microplasmas may be used to engineer laser-driven proton sources. In a second effort, tungsten micro-needle-targets were used at a peta-watt laser to produce few-keV x-rays and 10-MeV-level proton beams simultaneously, both measured to have only few-µm effective source-size. This source was used to demonstrate single-shot simultaneous radiographic imaging with x-rays and protons of biological and technological samples. Finally, the dissertation discusses future perspectives and directions for laser–microplasma interactions including non-spherical target shapes, as well as thoughts on experimental techniques and advanced quantitative image evaluation for the laser driven radiography.
