Background noise induced by ionizing radiation in the detectors of D2B-Aura
Abstract
The paper examines the nature of the degradation of the radiation detector of the D2B satellite due to background noise induced by ionizing radiation. Particular attention is given to the effects of radiation from an Sr-90-Y-90 source on photomultipliers and spiraltrons. In photomultipliers, two types of noise are observed: one type attributed to electrons, the other type to the production of gamma rays in the screens. Noise generation in MgF2 and LiF by the Cerenkov effect and fluorescence from the windows is considered.
