Abstract

The responsive quantum efficiency of semitransparent cesium telluride photocathodes has been found to be significantly increased by the application of high electric fields (a few MV m−1) such as are encountered in proximity-focused image converters. Measurements of the magnitude of the effect are presented as functions of applied field and of wavelength over the 120–800 nm range. An interesting anomaly was found in the pair-production region in the vacuum uv; otherwise, the results are fairly consistent with the effects of a simple Schottky lowering of the surface potential barrier of the photoemitter.
