Stability of Photocathodes

Applied Optics, 1973
The factors determining the stability of photocathodes containing alkali metals are discussed. If the necessary precautions are taken during the formation process, excellent shelf life performance can be obtained. By contrast, the stability in operation may be limited by several factors. The effects of cathode material, formation process, tube geometry,

Photocathodes

2017
Optical properties of photocathodes and their characterization in terms of absorptance, transparency, and reflectance in mixed dielectric media are presented. Photometric units and international standards are based on a specified white light source. The electromagnetic spectrum covers about a decade in wavelength and there is a relationship between ...

Ageing of S-10 Photocathodes

Applied Optics, 1973
The relative spectral sensitivity distributions of ten vacuum photodiodes with S-10 (Ag-Bi-O-Cs) photocathodes have been repeatedly measured over a period of up to 3 years. The results indicate that these photocathodes change considerably during the first 3 years of their life. The effect of these changes in photometric and colorimetric measurements is

Robust, long-life photocathodes

2015 40th International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz), 2014
Calabazas Creek Research, Inc. and the University of Maryland are developing high quantum efficiency (QE) reservoir cathodes for accelerators, free-electron lasers, ultra-fast electron microscopes and other applications. High QE materials are deposited on an emitter allowing diffusion of cesium from a reservoir. An integral heater provides a continuous

Analysis of Translucent and Opaque Photocathodes

Applied Optics, 1966
By an analysis of the photodetection process, the response of photodetectors to wide band, noncoherent light and guidelines for its improvement are determined. In this paper, the phenomenon of multiple reflections within the emitter of a reflecting-translucent and a reflecting-opaque photocathode is analyzed.

Carbon nanotube based photocathodes

Nanotechnology, 2008
This paper describes a novel photocathode which is an array of vertically aligned multi-walled carbon nanotubes (MWCNTs), each MWCNT being associated with one p-i-n photodiode. Unlike conventional photocathodes, the functions of photon-electron conversion and subsequent electron emission are physically separated.
