Description
Summary:A concept for the detection of ionizing radiation which utilizes the inherent high speed and large amplitude of the induced charge pulse in a semiconductor avalanche detector coupled with the tunnel diode element is described. It has been shown possible to digitally detect extremely low energy events even in high-current-induced noise backgrounds in the avalanche detector. Cryogenic cooling is not required. Detection is accomplished by use of the rate of rise and magnitude of the nuclear pulse (or alternatively a pulse of suitable amplitude and rate of rise generated by optical photons). The high-speed time domain allows discrimination against all noise-generated events because charge is not integrated in this scheme.
