Abstract
Détecteur ayant un écart uniforme et un réglage précis des angles entre les électrodes ainsi qu'une dimension finale précise. Il comprend un corps délimitant une cavité remplie de gaz ionisable et pourvu d'une fenêtre perméable aux radiations, des éléments espacés constituant des électrodes 41, 42, 43, 44 et des éléments isolants 40 interposés, et un matériau adhésif déposé sur des aires délimitées 54, 55, 56 de certaines parties adjacentes des éléments pour lier entre eux ces éléments et maintenir les dimensions obtenues. Application aux appareils de tomographie.
