Abstract

Competent experts provide a summary of the enormous progress achieved in the development of new detection methods of charged and neutral particles, and photons. These achievements were initiated by the advent of new particle colliders, e.g. the LHC at CERN but also by non-accelerator experiments. The present 2nd part of the handbook is devoted to the integration of detectors in large experiments, detectors for special applications, as well as the application of detectors in other fields like e.g. medicine, biology, applied physics and industry.

Abstract

A broad class of accelerators rests on the induction principle whereby the accelerating electrical fields are generated by time-varying magnetic fluxes. Particularly suitable for the transport of bright and high-intensity beams of electrons, protons or heavy ions in any geometry (linear or circular) the research and development of induction accelerators is a thriving subfield of accelerator physics. This text is the first comprehensive account of both the fundamentals and the state of the art about the modern conceptual design and implementation of such devices. Accordingly, the first part of the book is devoted to the essential features of and key technologies used for induction accelerators at a level suitable for postgraduate students and newcomers to the field. Subsequent chapters deal with more specialized and advanced topics.

Abstract

This exhaustive survey is the result of a four year effort by many leading researchers in the field to produce both a readable introduction and a yardstick for the many upcoming experiments using heavy ion collisions to examine the properties of nuclear matter. The books falls naturally into five large parts, first examining the bulk properties of strongly interacting matter, including its equation of state and phase structure. Part II discusses elementary hadronic excitations of nuclear matter, Part III addresses the concepts and models regarding the space-time dynamics of nuclear collision experiments, Part IV collects the observables from past and current high-energy heavy-ion facilities in the context of the theoretical predictions specific to compressed baryonic matter. Part V finally gives a brief description of the experimental concepts. The book explicitly addresses everyone working or planning to enter the field of high-energy nuclear physics.

Abstract

Periodic magnetic structures (undulators) are widely used in accelerators to generate monochromatic undulator radiation (UR) in the range from far infrared to the hard X-ray region. Another periodic crystalline structure is used to produce quasimonochromatic polarized photon beams via the coherent bremsstrahlung mechanism (CBS). Due to such characteristics as monochromaticity, polarization and adjustability, these types of radiation is of large interest for applied and basic research of accelerator-emitted radiation. The book provides a detailed overview of the fundamental principles behind electromagnetic radiation emitted from accelerated charged particles (e.g. UR, CBS, radiation of fast electrons in Laser flash fields) as well as a unified description of relatively new radiation mechanisms which attracted great interest in recent years. This are the so-called polarization radiation excited by the Coulomb field of incident particles in periodic structures, parametric X-rays, resonant transition radiation and the Smith-Purcell effect. Characteristics of such radiation sources and perspectives of their usage are discussed. The recent experimental results as well as their interpretation are presented.

Abstract

Laser driven proton beams are still in their infancy but already have some outstanding attributes compared to those from conventional accelerators. One such attribute is the typically low beam emittance. This allows excellent resolution in imaging applications like proton radiography. In the thesis by Thomas Sokollik a novel imaging technique - the proton streak camera - was developed and first used to measure both the spatial and temporal evolution of ultra-strong electrical fields in laser-driven plasmas. Such investigations are of paramount importance for the understanding of laser-plasma interactions and, thus, for optimization of laser driven particle acceleration. In particular, the present work investigated micrometer-sized spherical targets after laser irradiation. The confined geometry of plasmas and fields was found to influence the kinetic energy and spatial distribution of accelerated ions. This could be shown both in experimental radiography images and and in numerical simulations, one of which was selected for the cover page of Physical Review Letters.

Abstract

The neutrino is probably the most elusive elementary particle discovered so far. Its mass is very small and still unknown, and it is considered a key quantity in many theories beyond the Standard Model of particle physics. The smallness of the mass could be explained if neutrinos are, unlike all other particles, equal to their own antiparticles, thus following the conjecture of E. Majorana. The double beta decay without emission of neutrinos is a nuclear process that can happen only if the neutrino is a Majorana particle. Observation of this decay would therefore necessarily imply that neutrinos are Majorana particles and would set the mass scale, a breakthrough in our understanding of nature. The CUORE experiment will search for the neutrinoless double beta decay in 130Te, using 1 ton of TeO2 bolometric detectors. Bolometers are calorimeters that operate at cryogenic temperatures, able to measure the temperature rise produced by the energy release of an impinging particle. They feature good resolution and low background, making them excellent detectors to search for rare decays. The performances of the experiment are currently limited by temperature instabilities of the bolometers and by a poor understanding of their data. Mea­suring the energy deposited by a particle, in fact, is complicated and the shape of the signal depends on the energy. In this thesis a model of the signal of TeO2 bolometers is developed. It is able to explain the origin of the unwanted features that would limit the performances of CUORE. The application of the model to data from test bolometers led to great improvements of the results in terms of energy resolution, energy calibration, and signal shape discrimination. This thesis has been awarded at the Department of Physics, Universita di Roma - La Sapienza, Italy. With a Foreword by Professor Fernando Ferroni.

Abstract

A Search for Muon Neutrino to Electron Neutrino Oscillations in the MINOS Experiment is a tour de force that summarizes, clearly and in some depth, much of Ochoa’s vast body of work which has had a major impact on MINOS. The centerpiece of the thesis is the search for muon neutrino to electron neutrino oscillations, which would indicate a non-zero mixing angle between the first and third neutrino generations (θ13), currently the “holy grail” of neutrino physics.  The optimal extraction of the electron neutrino oscillation signal is based on the novel “library event matching” (LEM) method which Ochoa developed and implemented together with colleagues at Caltech and at Cambridge, which improves MINOS’ reach for establishing an oscillation signal over any other method. LEM will now be the basis for MINOS’ final results, and will likely keep MINOS at the forefront of this field until it completes its data taking in 2011. Ochoa and his colleagues also developed the successful plan to run MINOS with a beam tuned for antineutrinos, to make a sensitive test of CPT symmetry by comparing the inter-generational mass splitting for neutrinos and antineutrinos. Ochoa’s in-depth, creative approach to the solution of a variety of complex experimental problems is an outstanding example for graduate students and longtime practitioners of experimental physics alike. Some of the most exciting results in this field to emerge in the near future may find their foundations in this thesis, for which Ochoa was awarded the National Prize for Youth of Mexico in 2009. This Doctoral Thesis has been accepted by California Institute of Technology, Pasadena, USA.

Abstract

This thesis covers the few-cycle laser-driven acceleration of electrons in a laser-generated plasma. This process, known as laser wakefield acceleration (LWFA), relies on strongly driven plasma waves for the generation of accelerating gradients in the vicinity of several 100 GV/m, a value four orders of magnitude larger than that attainable by conventional accelerators. This thesis demonstrates that laser pulses with an ultrashort duration of 8 fs and a peak power of 6 TW allow the production of electron energies up to 50 MeV via LWFA. The special properties of laser accelerated electron pulses, namely the ultrashort pulse duration, the high brilliance, and the high charge density, open up new possibilities in many applications of these electron beams.
