1.06 Micron High Sensitivity IR Photocathode.

Abstract

The design and progress toward realization of a high sensitivity 1.06 micrometers field-assisted heterojunction photocathode are reported. Major emphasis has been placed on developing a Cs activation process for heterojunction devices and on a device fabrication technology which is consistent with Cs activation requirements. The first heterojunction devices (cold cathodes) were successfully activated and emission into vacuum was observed. Further work in developing a heterojunction photocathode structure for activation is recommended in order to realize the complete device and demonstrate the potential of the heterojunction photocathode.
