The JSR-14 Neutron Analysis Shift Register is a portable, fully computer controlled neutron analyzer that provides both neutron coincidence and multiplicity capability that is selectable through use of the provided setup software. The JSR-14 system functions as a direct replacement of the Mirion JSR-12 Neutron Coincidence Analyzer and the 2150 Multiplicity Module. The JSR-14 unit is based on a Los Alamos specification and shares the same chassis and form factor of the Mirion InSpector Multi-Channel Analyzer. The JSR-14 system is fully compatible with existing software operating with either the JSR-12 or Mirion 2150 Multiplicity Module. The JSR-14 system supports the same JSR-12 battery backed storage of system settings and 3000 data runs with time and date stamping of all data points by the system real-time clock. Also, the JSR-14 unit has the ability to operate in one of three different high voltage modes for portable and facility installed neutron counting applications. In addition, the JSR-14 system can be powered with an ac charger/adapter using facility provided ac power, or operated with the unique "Ping Pong" camcorder battery system found on the Mirion InSpector analyzer. When using ac power, the JSR-14 unit is protected from power loss for three hours by the use of a battery in the spare battery port. The memory buffer and hardware settings are protected by a lithium battery that is designed to operate for five years and easily replaced. Another feature is a programmable long delay of 1 and 4 milliseconds providing compatibility with the 2150 multiplicity module and JSR-12 coincidence settings.
