Abstract
This paper details the status of a program at Varian EOSP to develop high-sensitivity transmission photocathodes which function in the 0.95 - 1.65 micron wavelength range. One goal of the program is to develop a streak tube compatible cathode with greater than 1% quantum efficiency at 1.3 micrometers . Sealed tube results are presented. Measured performance characteristics include: cathode spectral response, room temperature cathode photoresponse stability, dark current, emitted electron energy distributions, photodiode resolution/MTF, and preliminary time response data. Finally, the paper includes a brief review of transferred electron photocathode physics and potential applications.
