AUTOMATIC GAIN STABILISATION AND TEMPERATURE COMPENSATION FOR ORGANIC AND/OR PLASTIC SCINTILLATION DEVICES Russian patent published in 2015 - IPC G01T1/40 

FIELD: measurement equipment.

SUBSTANCE: invention relates to radiation measuring devices, namely to a method of automatic gain stabilisation and temperature compensation in such devices. A detector and its associated method includes the first scintillation material having temperature dependence of light output and an output on the first energy level; the second scintillation material having temperature dependence of light output similar to the first scintillation material, an output on the second energy level and a detecting circuit. The first and the second outputs depend on radiation emitted from an ionising radiation source. The detecting circuit includes a common photoelectric multiplier configured for conversion of photons leaving the first scintillation material and the second scintillation material to electric pulses, a counter circuit configured for counting of electric pulses generated in the photoelectric multiplier with the first and the second scintillation materials, and a gain control circuit configured for tracking of electric pulses generated in the photoelectric multiplier with the second scintillation materials, and for adjustment of gain of the detector based on detection of drift of the output of the second scintillation material.

EFFECT: improving radiation detection accuracy.
