APPLICATION
The gamma–ray Detection Device is based on a HPGe detector with Electric Machine Cooling which is intended for the conversion of Gamma-ray quantum energy using amplitude electric signals and their amplification for further registration with a nuclear physics apparatus. It was specifically developed for long, continuous operations.
FEATURES
-
No liquid nitrogen necessary;
-
Detection of radiation possible in any spatial orientation;
-
Automatic restart after power supply switch-off;
-
Long-duration continuous function;
-
Coaxial or planar HP(Ge) detector can be used.
COMPLETE SET
-
Detection device consisting of cryostat, HP(Ge) detector crystal, temperature sensor and heat exchanger;
-
Gas compressor cooling system with built-in cryocontroller for the provision of automatic monitoring and control of operating modes for HP(Ge) detector and cryosystem;
-
High pressure gas pipes for connecting the cryosystem to the Detection Unit heat exchanger;
-
-
Emulation and analysis Software.
