Description

Photocathodes capable of producing highly spin polarized electrons beams are required for both high energy and nuclear physics experiments. In this talk, we report on the commissioning of a new UHV vacuum system for photocathode characterization, which includes a retarding field Mott polarimeter for the measurement of electron spin polarization. We will illustrate the design of III-Vs superlattice structures equipped with Distributed Bragg Reflector and present the measurements of electron spin polarization and quantum efficiency of emitted electrons from these structures
