AN INITIAL GAMMA-RAY SPECTROGRAPH,

Abstract

The feasibility of an initial gamma-ray spectrograph has been investigated. An instrument based on the magnetic analysis of Compton electrons is presented as having suitable attributes for use in the laboratory or in the field and for the measurement of gamma spectra from weapons or pulsed reactors. The instrument is designed for an energy range from 1 to 12 Mev and may be useable over the range from 0.25 to 25 Mev. Use of the natural focal properties of uncollimated Compton electrons in a semicircular beta-ray spectrograph is proposed, and theoretical and experimental results are presented on the performance of such an instrument. The resolution that can be obtained is approximately 40 kev, the instrument can be used at arbitrarily high rates, and the sensitivity is very low. In a typical situation 10 to the 15th power gamma rays might be just detectable. (Author)
