4096 Channel Time Analyzer with Variable Channel Width

Abstract

A time analyzer for neutron time-of-flight studies is described. An ``accordion'' feature permits different channel widths in adjacent time regions. Eight independent selections of channel width for each of the 16 regions of 256 channels are provided, ranging by factors of 2 from 125 nsec to 16 μsec. A channel width multiplier increases all the widths by a factor of 8, 4, 2, or 1. Deadtime is 5 μsec per event stored. Channel capacity is 262 143 counts. Readout is punched paper tape, followed by verify in a tape reader.
