Abstract

This article describes a study on the influence construction and technology on the time stability of neutron sensors developed at the Institute of Electron Technology, and was prepared the need to eliminate the dark current growth in long-term use, not associated with radiative exposures. After analyzing the construction of detectors makes some changes to technological processes. To improve the assembly technology changed the type of converter (hard wax is replaced with a soft petroleum jelly) and introduced the foam insert to the casing of the sensor in order to avoid mechanical stresses in the structure. These stresses occur as a result of thermal shrinkage of wax (almost abrupt change of state from liquid to crystalline phase), which caused the piezoelectric effect. After conducting structural and technological changes detectors were long-term electric load.
