A 2000-Channel Analyzer for Neutron Spectroscopy

Abstract

A 2000-channel time-of-flight analyzer for neutron spectroscopy is described. The analyzer is designed for use with pulsed accelerators operating at approximately 60 cps. Channel widths of 0.1 μsec and a Head time of 0.8 μsec are obtained. A fast electrostatic memory is used to record data with a minimum of dead time, and a slower larger capacity magnetic drum memory is used to read out the electrostatic memory and accumulate data between bursts. The electrostatic memory system which was developed at Columbia University is described in detail.
