The possibility of extending the operating range of semiconductor-detector instruments into the low-energy region
Abstract
Silicon surface-barrier detectors, designed to measure protons in the upper atmosphere, were tested on a proton accelerator in the 10-100 keV energy range. It is shown that detectors made of silicon with specific resistances of 3000, 200, and 100 ohm cm provide for an energy resolution of 7-12 keV, making possible the detection of protons with minimum energies (9-15 keV) under laboratory conditions. Attention is given to the main factors hampering the use of semiconductor detectors with a low detection threshold in rocket experiments.
