Charge Multiplication in Silicon Radiation Detectors under Dense Irradiation

Charge multiplication at low field has been studied by fission fragments spectroscopy in ion-implanted Si-detectors. Also, various types of Si-detectors were used at CERN to measure a pulsed muon flux of high density, and again multiplication was observed above a flux threshold which depends on the detector design. In the absence of the gold contact no multiplication occurs.
