Synchrotron Backgrounds for Laserwire Detector in Upstream Polarimeter Chicane

Woods, M. (SLAC) ; Moffeit, K. (SLAC)

Abstract: Synchrotron radiation (SR) backgrounds for the Laserwire Detector in the upstream Polarimeter chicane are estimated, due to the first dipoles in the chicane. For nominal (RDR design) operation at 250 GeV, the SR critical energy is 4.1 MeV and the total SR power incident on the laserwire detector is ~5.5E-6 of the beam power. A laserwire detector in the 0-degree line will have unacceptably large backgrounds. A preferred solution is to instead detect the Compton-scattered electrons.
