Polarized Electron Source Group


The Polarized Electron Source Group is responsible for generating the polarized electrons used at the Stanford Linear Accelerator Center (SLAC). This is accomplished by illuminating a photocathode with circular polarized light. The Polarized Electron Source Group personnel is responsible for maintaining the Polarized Light Source (PLS) and the photo injector, which creates the polarized electrons for fixed target experiments at SLAC. The photoinjector also delivers the unpolarized electron beam required by the PEPII program. Besides insuring uninterrupted operation of the injector, a considerable amount of R&D is carried out in the area of laser system and photocathode development.
