Two methods to measure the e/sup /plus minus// polarization at PEP
Backward Compton scattering of circularly polarized photons from an e/sup /plus minus// beam can be used to measure the polarization of that beam. We describe a simple, compact fast monitor that measures the beam polarization at P.E.P. by scattering a laser beam off the e/sup /plus minus// bunches and detecting the backscattered photons. We also present graphs of how the /d/sigma//d/Omega//of the electromagnetic processes e/sup +/e/sup/minus// /yields/ e/sup +/e/sup/minus//, /mu//sup +//mu//sup/minus//, /tau//tau/ is modified by the transverse polarization of the initial state particles.
