Self-powered gamma radiation detector

Creators

Description

The detector is designed for radiation measurement in the reactor core; it meets the NRC requirements. It consists of a closed, tube-shaped cartridge as collector, a central rod as emitter and an isolation between both formed by vacuum or air. In order to increase its γ-sensitivity its dimensions are optimized and the emitter consists of platimun, the collectors of Inconel. (DG)

Abstract (German)

Der Detektor dient der Strahlenflussmessung im Reaktorcore unter Erfuellung der NRC-Bestimmungen. Er besteht aus einer verschlossenen, roehrenfoermigen Huelse als Kollektor, einem zentralen Stab als Emitter und einer Isolation zwischen beiden aus Vakuum oder Luft. Zur Erhoehung der γ-Empfindlichkeit sind seine Abmessungen optimiert und der Emitter besteht aus Platin, der Kollektor aus Inconel. (DG)
