GAMMA RAY SPECTROMETER, Certification : CE Certified

GAMMA RAY SPECTROMETER TYPE : GR 612 manufactured by Nucleonix

Systems is a state-of-art microcontroller based modular unit consisting of LV Power

supply card, High Voltage Card, Linear Amplifier card, Single Channel Analyser and

Controller based Timer/Counter Cards housed into a single enclosure.

The Gamma Ray Spectrometer GR 612 essentially accepts the input pulses from a

Scintillation Detector which gives out electrical pulses proportional in amplitude to the

incident Gamma energy. Low Voltage unit provides the necessary LV supplies to

power up the circuits for their functionally. The High Voltages card provides the

necessary bias for scintillation detector. The detector output amplified by Linear

Amplifier is fed to the Single Channel Analyser for pulse height analysis. The output

events from SCA are counted for a preset time in Controller card. SCA is an important unit

in GRS which scans the entire Gamma Spectrum. Controller card has built-in Six digit

serial counter & under programme control it can store the data in CPS, CPM & counts for

preset time mode. It has three modes of data. Readings upto 1000 readings can be

stored and recalled on to the LCD dotmatrix display. Also data counts can be printed

directly onto a printer through printer port or downloaded into a PC through serial port

under software control.
