A cosmic-ray dosimeter with a semiconductor detector
Abstract
The Intercosmos-17 cosmic-ray dosimeter is described, and a circuit diagram of the device is presented. The operation of the instrument is characterized by the extraction, enhancement, and processing of information in a digital form with rejection of noise signals. When an optimal thickness is chosen for the sensitive region of the detector, the amplitude of signals from charged particles of minimally ionized cosmic rays can exceed the amplitude of noise pulses from the detector and preamplifier. This makes it possible to achieve a negligibly small value of subthreshold losses of useful information and an almost total discrimination of noise pulses in measuring cosmic-ray charged particles.
