PURPOSE
Registration and transformation of gamma-radiation energy into electric signals
of corresponding amplitude so that they can be later processed.

APPLICATION
- Construction of spectrometric systems for laboratory and industrial purposes.
- Detectors of the BDS-G type can be used in various scientific and economic fields for qualitative and quantitative analysis of gamma-emitting radionuclide samples
COMPONENTS
Detection units are produced on the base of the assembly "scintillation
crystal NaI(TI) - PMT" and consist of:
- pre-amplifier, driver-amplifier with parameters of output impulses that
enable to transmit them directly to the input of the amplitude-digital converter
(multi-channel analyzer)
- high-voltage power supply
- a system for stabilization of the measurement channel based on a special
LED with the function of temperature compensation of converter characteristic
