Title

A Source and Detector of Radiation in the Wavelength Region 1500-50 Angstroms Suitable for Radiation Effects Studies on Materials In Vacuo

Description

This report describes a source and detector of vacuum ultraviolet radiation in the wavelength range 1500 - 50 angstroms are described which 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 10-9 mm Hg.
