Abstract

Dispositif de détection et de localisation de rayonnements neutres, comprenant un détecteur 15 et une chambre à dérive d'électrons 14. La chambre comporte deux électrodes 18 et 19. Les électrodes de création du champ électrique statique de dérive sont constituées chacune par une nappe de conducteurs parallèles disposés dans un même plan perpendiculaire à l'axe. Les conducteurs d'une même nappe sont portés à des potentiels différents échelonnés pour effectuer les équipotentiels correspondant à un champ électrostatique centre sur l'ouverture du collimateur 12. Applications à la cristallographie et à l'imagerie nucléaire.
