Optical Pumping of Metastable Helium Atoms in Polarized Electron Sources
I. Brissaud1

In this paper we present a comparison between the Orsay and Rice University polarized electron sources. Different explanations of the polarization degradation are discussed for the two cases. For the Rice source radiation, trapping can account for the observed reduction in polarization because of the high absorption cross sections associated with the D1 transition. Some improvements are proposed that might increase the electron polarization.
