PROGRESS ON LEAD PHOTOCATHODES FOR SUPERCONDUCTING INJECTORS.

PDF Version Also Available for Download.

Description

We present the results of our investigation of bulk lead, along with various types of lead films, as suitable photocathode materials for superconducting RF injectors. The quantum efficiency of each sample is presented as a function of the photon energy of the incident light, from 3.9 eV to 6.5 eV. Quantum efficiencies of 0.5% have been obtained. Production of a niobium cavity with a lead-plated cathode is underway.
