A SOURCE AND DETECTOR OF RADIATION IN THE WAVE-LENGTH REGION 1500-50 ANGSTROMS SUITABLE FOR RADIATION EFFECTS STUDIES ON MATERIALS IN VACUO

Abstract

A source and detector of vacuum ultraviolet radiation in the wavelength range 1500 - 50 angstroms are described; they are being developed for radiation effects studies on materials in vacuo. The principle of the radiation source is the repetitive pulsed discharge of capacitor stored energy into a ceramic discharge tube. A very hot plasma will thus be generated which will emit vacuum ultraviolet radiation by Bremsstrahlung - like processes. The principle of the radiation detector is photoelectric emission from a photocathode exposed directly to the radiation in vacuo. The pulsed output current from the multiplier phototube will be measured with a finite integrator. The radiation source and detector are designed to be finally incorporated in an environmental test chamber capable of being evacuated to a working pressure of 10 to the 9th power mm Hg. (Author)
