Book excerpt: In the Linear Collider design, the positron capture system includes a positron production target, followed by an adiabatic matching device (solenoid), a pre-linac with solenoidal focusing, and a linac with quadrupole focusing before injection into a positron damping ring. Two schemes for positron production have been studied: (1) a conventional approach with high-energy electron beam interacting with a high-Z target and (2) polarized positron production using polarized photons generated in a helical undulator by a primary collider electron beam which then interact with a positron production target. The capture efficiencies for both schemes are compared. Various parameters affecting the positron capture are analyzed.

Available in PDF, EPUB and Kindle. Book excerpt: In the Linear Collider, the positron capture system includes a positron production target, an adiabatic matching device (AMD), and a linac to accelerate positrons up to the injection energy of the positron damping ring. Efficiency of the positron collector is defined by the number of positrons accepted into the damping ring. Analysis of the positron collection system is performed using a conventional scheme, where positrons are produced by a high-energy electron beam hitting the high-Z target. The collection system has been optimized to insure high positron capture into the 6-dimensional acceptance of the damping ring. Various parameters affecting the positron capture are analyzed.

Book excerpt: The requirements of a positron source for a linear collider are briefly reviewed, followed by methods of positron production and production of photons by electromagnetic cascade showers. Cross sections for the electromagnetic cascade shower processes of positron-electron pair production and Compton scattering are compared. A program used for Monte Carlo analysis of electromagnetic cascades is briefly discussed, and positron distributions obtained from several runs of the program are discussed. Photons from synchrotron radiation and from channeling are also mentioned briefly, as well as positron collection, transverse focusing techniques, and longitudinal capture. Computer ray tracing is then briefly discussed, followed by space-charge effects and thermal heating and stress due to showers. (LEW).

Download or read book Linear Collider Physics In The New Millennium written by Keisuke Fujii and published by World Scientific. This book was released on 2005-11-21 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high energy electron-positron linear collider is expected to provide crucial clues to many of the fundamental questions of our time: What is the nature of electroweak symmetry breaking? Does a Standard Model Higgs boson exist, or does nature take the route of supersymmetry, technicolor or extra dimensions, or none of the foregoing? This invaluable book is a collection of articles written by experts on many of the most important topics which the linear collider will focus on. It is aimed primarily at graduate students but will undoubtedly be useful also to any active researcher on the physics of the next generation linear collider.

Download or read book Precision Electroweak Physics at Electron Positron Colliders written by Stefan Roth and published by Springer Science & Business Media. This book was released on 2007 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This up-to-date volume reviews the recent contributions of electron-positron colliders to the precision test of the electroweak Standard Model. In particular, it contains a short summary of the measurements at the Z resonance and gives an overview of the electroweak processes above the Z. Subsequently, the measurement of the W mass at LEP is discussed in detail. The implications for the precision test of the Standard Model are presented, giving the status of the global electroweak fit before the startup of Large Hadron Collider. The final chapters give an outlook on the electroweak physics at a future linear collider. The book also features many illustrations and tables. Readers obtain a coherent overview of the results of 20 years of electroweak physics conducted at electron-positron colliders.

Available in PDF, EPUB and Kindle. Book excerpt: It has been very clear from the beginning of studies for future linear colliders that the conventional positron source approach, as exemplified by the SLC source, is pushing uncomfortably close to the material limits of the conversion target. Nonetheless, since this type of positron source is better understood and relatively inexpensive to build, it has been incorporated into the initial design studies for the JLC/NLC. New ideas for positron sources for linear colliders have been regularly reported in the literature and at accelerator conferences for at least a decade, and indeed the recirculation scheme associated with the VLEPP design is nearly two decades old. Nearly all the new types of positron sources discussed in this workshop come under the heading of crystals (or channeling), undulators, and Compton. Storage ring and nuclear reactor sources were not discussed. The positron source designs that were discussed have varying degrees of maturity, but except for the case of crystal sources, where proof of principle experiments have been undertaken, experimental results are missing. It is hoped that these presentations, and especially the recommendations of the working groups, will prove useful to the various linear collider groups in deciding if and when new experimental programs for positron sources should be undertaken.

Download or read book International Linear Collider ILC written by Alexey Drutskoy and published by Morgan & Claypool Publishers. This book was released on 2018-11-26 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Linear Collider (ILC) is a mega-scale, technically complex project, requiring large financial resources and cooperation of thousands of scientists and engineers from all over the world. Such a big and expensive project has to be discussed publicly, and the planned goals have to be clearly formulated. This book advocates for the demand for the project, motivated by the current situation in particle physics. The natural and most powerful way of obtaining new knowledge in particle physics is to build a new collider with a larger energy. In this approach, the Large Hadron Collider (LHC) was created and is now operating at the world record center of-mass energy of 13 TeV. Although the design of colliders with a larger energy of 50-100 TeV has been discussed, the practical realization of such a project is not possible for another 20-30 years. Of course, many new results are expected from LHC over the next decade. However, we must also think about other opportunities, and in particular, about the construction of more dedicated experiments. There are many potentially promising projects, however, the most obvious possibility to achieve significant progress in particle physics in the near future is the construction of a linear e+e- collider with energies in the range (250-1000) GeV. Such a project, the ILC, is proposed to be built in Kitakami, Japan. This book will discuss why this project is important and which new discoveries can be expected with this collider.
