Abstract
L'invention concerne un localisateur d'impact de particules, à semi-conducteur, et les tubes images incorporant ce localisateur. Dans le localisateur de l'invention, les collecteurs appliqués sur la couche résistive recouvrant l'une des faces du semi-conducteur sont morcelés en plusieurs parties de surface inégale. Seuls les courants recueillis sur certaines de ces parties lors de l'impact d'une particule sont utilisés intégralement dans le calcul de la position de cet impact, les courants recueillis sur les autres parties n'étant que partiellement utilisés ou pas du tout. Ceci réduit la distorsion observée dans les dispositifs de ce genre, tels que connus à ce jour. Application à la médecine nucléaire, en rayonnement gamma notamment, avec un tube comprenant un écran scintillateur à l'entrée et un localisateur comme écran de sortie.
