Abstract
In this paper, we briefly describe measurements of the 60 - 200 eV photoemission from Caesium Iodide, Gold, and Aluminum photocathodes made on beamline 6.1 of the SERC Daresbury synchrotron radiation source (SRS). Measurements were made near grazing incidence using both s- (electric vector perpendicular to the plane of incidence) and p- polarized (electric vector parallel to the plane of incidence) radiation. Our data supports the existence of an 'x-ray vectorial effect'--a pronounced linear polarization dependence of the photoyield--observed in earlier experiments at Leicester and Columbia Universities and elsewhere. For CsI, novel measurements are also reported of: radiation damage and annealing, and the temperature dependence of the photoyield.
