Title (EN) SELF-POWERED NUCLEAR DETECTOR
(FR) DÉTECTEUR NUCLÉAIRE À ALIMENTATION AUTONOME
Abstract: front page image
(EN)A self-powered neutron detector having an emitter with a slightly negative bias voltage that assures that an increase in the electrons that enter the insulator are counted and decreases or eliminates the gamma induced prompt signal. Variations in the size of the bias is used as a diagnostic tool to estimate the gamma induced prompt signal.
(FR)La présente invention concerne un détecteur de neutrons à alimentation autonome comportant un émetteur ayant une tension de polarisation légèrement négative qui garantit qu'une augmentation des électrons qui entrent dans l'isolateur est comptée et qui diminue ou supprime le signal prompt induit par des rayons gamma. Les variations de l'importance de la polarisation sont utilisées à titre d'outil de diagnostic permettant d'estimer le signal prompt induit par des rayons gamma.
