Abstract
A method and circuit for controlling the amplification in a radiation-detecting avalanche diode in which the diode generates electrical signals dependent upon the received radiation. These electrical signals are fed to evaluating means and a control signal is derived from the diode having a frequency which differs from the frequency used in the evaluation means. The amplitude of the control signal is compared with a preset value and the supply voltage of the diode is varied in dependence upon this comparison for controlling amplification of the diode.
