Polarization studies of strained GaAs photocathodes at the SLAC Gun Test Laboratory

PDF Version Also Available for Download.

Description

The SLAC Gun Test Laboratory apparatus, the first two meters of which is a replica of the SLAC injector, is used to study the production of intense, highly-polarized electron beams required for the Stanford Linear Collider and future linear colliders. The facility has been upgraded with a Mott polarimeter in order to characterize the electron polarization from photocathodes operating in a DC gun. In particular, SLAC utilizes p-type, biaxially strained GaAs photocathodes which have produced longitudinal electron polarizations greater than 80% while yielding pulses of 5 A/sq cm at an operating voltage of 120 kV. Among the experiments performed include ... continued below

Among the experiments performed include studying the influences of the active layer thickness, temperature, quantum efficiency and cessation on the polarization. The results might help to develop strained photocathodes with higher polarization.
