Description

The JSR-12 Neutron Coincidence Analyzer separates coincidence neutron events from random neutron events, and thus provides a method of counting neutron signatures from spontaneously fissioning isotopes or induced fission from fissile isotopes. At the conclusion of each counting interval (operator selected), the unit provides information on total counts, reals plus accidentals and accidentals as displayed on the front panel. Most significantly, it does this without substantial deadtime by a unique technique in which a new coincidence gate is started for each neutron event presented at the input.

The JSR-12 has an internal, battery-backed time-of-day and day-of-year realtime clock and data RAM which permits time and date marking of all stored data for power-down storage of up to 3000 data runs. The firmware resides in EPROM.
