Description

Suitable for semiconductor detector (559 921) and Rutherford scattering chamber (559 56). For bias voltage supply and for amplification and processing of voltage pulses. Analogue output with energy-proportional pulses for connection of the VKA box (524 058) for α energy spectra. Digital discriminator output for the reading of rectangular pulses provided by particles whose energy is above an adjustable limit. With stand rod for support in the stand.
