Description

For scintillation counter (559 901), for accommodation in standing and lying position.
It consists of a high-resistance voltage divider for supplying the dynodes of the secondary electron photomultiplier, a derivative unit and an impedance converter. Pulse amplitude proportional to the radiation energy recorded by the scintillator. Voltage divider for high-voltage measurement. With three fitted screened cables for signal output, high voltage supply and low-voltage supply for electronics.
