Available in PDF, EPUB and Kindle. Book excerpt: This note is a summary of the author's views on the subject of effective temperatures (and the Unruh temperature in particular) in accelerators. Unruh analyzes the response to vacuum fluctuations of a linearly accelerated two-level atom serving as a detector and shows that the relative populations of the two states are given by a boltzmann factor with kT=[h-bar]a/2[pi]c, where a is the acceleration. The inference is that the detector is immersed in a black-body spectrum of Unruh radiation at the Unruh temperature. He refers to these ideas as the Unruh effect.

Available in PDF, EPUB and Kindle. Book excerpt: The 9th International Symposium on High Energy Spin Physics was held in Bonn, 6-15 September 1990, with the Physikalisches Institut der Universitat Bonn as the host. The symposium was preceded by a series of four workshops on • polarized electron sources and electron spin polarimeters • Siberian snakes and polarization in circular machines • polarized gas targets • polarized solid targets. 160 participants from 11 countries, among them many young physicists, came together and discussed mainly technological spin problems. The high level of participation indicates that workshops combined with the symposium are attractive not only for people who plan and prepare polarized beams and targets but also for experimentalists and theorists dealing with high energy spin physics. At these workshops many very interesting and important recent results were presented and reviewed. Thus we hope these proceedings will be valuable to many researchers in these fields. The Organizing Committee would like to thank all participants, in particular the speakers and the session chairmen, for their contributions to the workshops and for helping to create a lively and stimulating atmosphere. Special thanks go to the organizers - W. Haeberli, S. Mango, E. Reichert, E. Steffens, W. Thiel, U. Wienands - for their cooperation in preparing and running these workshops. We gratefully acknowledge the enthusiastic help of the members of our institute in preparing and running the conference and the workshops, especially Mrs. D. FaSbender, Mrs. E. Wendorf, Mrs. J. Wetzel, and Dr. U.Idschok.

Available in PDF, EPUB and Kindle. Book excerpt: This book examines the acceleration and storage of polarized proton beams in cyclic accelerators. Basic equations of spin motion are reviewed, the invariant spin field is introduced, and an adiabatic invariant of spin motion is derived. The text presents numerical methods for computing the invariant spin field, and displays the results in numerous illustrations. This book offers a more lucid view of spin dynamics at high energy than has hitherto been available.
Download or read book Planning and Prototyping for a Storage Ring Measurement of the Proton Electric Dipole Moment written by and published by . This book was released on 2015 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron and proton EDM's can be measured in "frozen spin" (with the beam polarization always parallel to the orbit, for example) storage rings. For electrons the "magic" kinetic energy at which the beam can be frozen is 14.5 MeV. For protons the magic kinetic energy is 230 MeV. The currently measured upper limit for the electron EDM is much smaller than the proton EDM upper limit, which is very poorly known. Nevertheless, because the storage ring will be an order of magnitude cheaper, a sensible plan is to first build an all-electric electron storage ring as a prototype. Such an electron ring was successfully built at Brookhaven, in 1954, as a prototype for their AGS ring. This leaves little uncertainty concerning the cost and performance of such a ring. (This is documentedin one of the Physical Review papers mentioned above.).

This book was released on 1990 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a storage ring with a purely horizontal spin and a Siberian Snake, the spin matching conditions are similar to the spin matching conditions for vertical polarization; a combination of beam bumps has to be found which compensate the depolarizing effects. These bumps compensate the random emission of synchrotron emission on the spin. The aim of this paper is to define spin matching conditions that compensate this effect.

Available in PDF, EPUB and Kindle. Book excerpt: The 9th International Symposium on High Energy Spin Physics, held in Bonn, 6-15 September 1990, attracted 280 participants from 16 countries. This meet ing covered not only fundamental experimental and theoretical spin phenomena but also technological developments in polarized beams and targets. For the first time intermediate energy spin physics with electron machines was discussed extensively. Highlights included the work on polarized high energy electron beams at LEP and TRISTAN and the failure of the standard model in connection with spin phenomena, in particular the growth of the spin asymmetry in violent proton-proton scattering. Also the presentation of different models in con nection with the still-unsolved 'proton spin crisis' and the proposals for four different experiments to determine the spin structure functions caused lively and sometimes controversial discussions. The Organizing Committee would like to thank all speakers for their excel lent talks, the conveners for the organization of the parallel sessions, and the International Advisory Committee for their advice. Four workshops preceded the symposium. 160 participants, among them many young physicists, discussed mainly technological spin problems. These papers are published in separate proceedings. We gratefully acknowledge the enthusiastic help of the members of our institute in preparing and running the conference and the workshops, especially Mrs. D. FaSbender, Mrs. E. Wendorf, Mrs. J.

Download or read book Quantum Aspects Of Beam Physics Advanced Icfa Beam Dynamics Workshop written by Pisin Chen and published by World Scientific. This book was released on 1999-04-19 with total page 818 pages. Available in PDF, EPUB and Kindle. Book excerpt: The frontiers of beam research point to increasingly high energy, greater brightness and lower emittance beams with ever-increasing particle species. These demands in turn have triggered a rapidly growing number of beam phenomena that involve quantum effects. Concurrently, the violent accelerations which are becoming available through novel accelerator research may, perhaps, help to investigate fundamental physics associated with general relativity. In view of these exciting developments and the important role they may play in the next century, the world's first conference on the 'Quantum Aspects of Beam Physics', held at Monterey, California, in January 1998, attracted a broad spectrum of experts from beam physics, particle physics, laser science, astrophysics, condensed matter physics, nuclear and atomic physics. At the end of the meeting, a new term 'quantum beam physics' was coined.This book collects together the excellent reviews and papers on new advances in the field which were presented during the workshop. It should be a valuable reference to all physicists interested in the frontiers of quantum beam physics.
