Beamstrahlung Monitors at Slc*
Some properties of beamstrahlung are discussed, and plans to observe the effect at SLC by the use of Cherenkov counters are illustrated. Invited talk presented at the International Conference on Advances in Experimental Methods for Colliding Beam Physics, Stanford, California, March 9-13, 1987 * Work supported by the Department of Energy, contract DE A C 0 3 7 6 SF 00 5 15.
متن کاملBeam-loss Monitors Tn the Slc Final Focus'
Beam-loss monitors in the SLC Final Focus System &e used for protection of accelerator and detector components, optimizing adjustment of beam halo collimators, and as diagnostics of beam size and halo. Construction of a variety of monitors based on discrete ion chambers, proportional tubes, continuous 'ion chambers, and signals from the Mark II detector is reported. The interfaces to the SLC co...

متن کاملDisruption, Beamstrahlung, and Beamstrahlung Pair Creation*
The two major effects from the interaction of e-e+ beams beamstrahlung and disruption are reviewed, with emphasis on flat beam collisions. For the disruption effects we discuss the luminosity enhancement factor, the maximum and rms disruption angles, and the “kink instability”. All the results are obtained from computer simulations, and scaling laws based on these are deduced whenever possible....
متن کامل+ 2γ at Slc/lep Energies *
We use the spinor methods of the CALKUL collaboration, as realized by Xu, Zhang and Chang, to calculate the differential cross section for e + e − → e + e − + 2γ for c.m.s. energies in the SLC/LEP regime. An explicit complete formula for the respective cross section is obtained. The leading log approximation is used to check the formula. Applications of the formula to high precision luminosity ...
