BDS-B-150 |
COMPONENTS
Detectors are produced on the basis of the "plastic scintillator – PMT" assembly and consist of:
a pre-amplifier, driver-amplifier with parameters of output pulses allowing their direct transmission to the amplitude-to-digital
- a converter input (multi-channel analyzer);
- a high-voltage power supply;
- a system for stabilization of the measurement channel based on a special LED with the function of temperature
compensation of the converter characteristic
