Abstract
Different methods for the preparation of K-Cs-Sb photocathodes, suitab le for electron sources in RF guns, are described in detail. The resul ting material has been characterized by Auger depth profiling techniqu e, and by its spectral response in the 250-600 nm range, as well. The results of lifetime experiments under operational and ''laboratory'' c onditions are presented. The role of CO2 in reducing the operational l ifetime of the photocathodes and that of O-2 in improving the long-wav elength response are investigated.
