SPECIAL XUV DETECTORS FOR PHOTOELECTRON EMISSION STUDIES.
Abstract
Windowless detectors combining retarding potential analyzers and CBS type 14-stage linear focussed electron multipliers were designed and built for laboratory XUV studies. These detectors were designed to study photoemission generated by incident and transmitted photons. Included were single and remotely controlled eight cathode units. A substantial counting plateau and a single electron peak or knee was observed during operation of these devices. Thin aluminum film development demonstrated the difficulty in making thin films with similar photoelectric properties in both sides. The feasibility of using a thin aluminum film coated with a layer of low density KCl as a combination XUV filter and high electron multiplier stage was demonstrated. Rugged detectors using planar retarding potential analyzers and electron multipliers were designed to study the electron energy (50eV) distribution within and above the earth's atmosphere. (Author)
