STUDY OF EVOLUTION OF ACTIVE VOLUME IN IRRADIATED SILICON DETECTORS

Abstract Light pulses emitted by a red (670 nm) Light Emitting Diode (LED) have been used to study the charge collection properties of non-irradiated and irradiated n-type silicon detectors. The advantages of red LED light pulses, compared to low-range alpha particles, are the availability of an external trigger and a very shallow distribution of the created e–h pairs (
