MULTICHANNEL SEMICONDUCTOR DETECTOR FOR DETECTING ALPHA-PARTICLES IN STATIC VACUUM NEUTRON GENERATOR AND DETECTING ELEMENT FOR SAID DETECTOR

摘要

FIELD: physics.;SUBSTANCE: multi-element semiconductor detector for detecting alpha-particles in a static vacuum neutron generator, having a detector housing, a semiconductor crystal wafer placed perpendicular to the stream of alpha-particles and detecting elements with electric contacts and current leads placed on both sides of the semiconductor crystal wafer. The semiconductor crystal wafer is configured to accommodate on both its sides all detecting elements with electric contacts and current leads, and is mounted around the periphery of a ceramic wafer, at whose centre there is an opening through which alpha-particles fall on the detecting elements; the ceramic wafer is mounted on a chassis, also having an opening through which alpha-particles fall on the detecting elements; the detecting elements are in form of strips made on the semiconductor crystal wafer by ion implantation, and electric contacts are made by sputtering metal onto the detecting elements. The strips of detecting elements on the same side of the semiconductor crystal wafer are parallel to each other and perpendicular to strips of detecting elements on the other side of the semiconductor crystal wafer.;EFFECT: high reliability and sensitivity of the detector.;4 cl, 2 dwg
