Preliminary Results from a Superconducting Photocathode Sample Cavity / Kneisel, Peter ; Lefferts, Richard ; Lipski, Andrzej ; Sekutowicz, Jacek
Pure niobium has been proposed as a photocathode material and recently a successful test has been conducted with a niobium single cell cavity to extract photo-currents from the surface of this cavity. However, the quantum efficiency of niobium is ~2·10-4, whereas electrodeposited lead has a ~15 times higher quantum efficiency. [...]

Progress on Lead Photocathodes for Superconducting Injectors / Smedley, John ; Kneisel, Peter ; Langner, Jerzy ; Lefferts, Richard ; Lipski, Andrzej ; Rao, Triveni ; Sekutowicz, Jacek ; Strzyzewski, P
We present the results of our investigation of bulk, electroplated and vacuum deposited lead as suitable photocathode materials for superconducting RF injectors. The quantum efficiency of each sample is presented as a function of the wavelength of the incident light, from 310 nm to 190 nm. [...]
