Abstract

This paper details the status of a program at Intevac ATD to develop high sensitivity transmission photocathodes which function in the 0.95-1.7 micron wavelength range. The goal of the program is to develop this technology for use with both imaging and nonimaging detectors. Sealed tube results are presented. Measured performance characteristics include: cathode spectral response, dark current, linearity, and the effects of cooling. A brief discussion of planned development, potential applications, and simple modeling illustrating the advantages of the proposed detectors are included.
