Abstract

Fast energy spectrum and transverse beam profile monitoring systems have been tested at the SLC (Stanford Linear Collider). The signals for each system are derived from digitizations of images on phosphor screens. Individual beam bunch images are digitized in the case of the transverse profile system and synchrotron radiation images produced by wiggler magnets for the energy spectrum. Measurements are taken at 2-s intervals. Feedback elements have been installed for future use and consist of RF phase shifters to control the energy spectrum, and dipole correctors to control the beam launch into the linac affecting the transverse beam profile. Details of these systems, including hardware, timing, data acquisition, data reduction, measurement accuracy, and operational experience, are presented
