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.
PurityBuilt-in USB port facilitates connection to PC,Built-in USB port facilitates connection to PC,Heating rates are 10°c / sec to 40°c / sec. Etc.
Thermo luminescence Reader Type TL1009 designed and offered by NUCLEONIX SYSTEMS is a versatile controller based unit, facilitating the user to subject the TL sample under study to the desired heating profile, to record the digitized TL glow curve. This unit stores both integral value and digitized glow curve into EEPROM memory.
This unit records the data in 200 channels, temp, TL intensity & Run time values.
Entire electronics including PMT, HV bias, Temperature controller circuit, Heater transformer heater strip, sample drawer assembly, data acquisition electronics is all integrated into a single enclosure.
The user interface to the unit is through a powerful software GUI, coded in .net which runs on Windows platform. This system essentially works as a PC controlled TLD reader with command buttons and dropdown menus defined for various functions.
