Disclosed is a microchannel plate having excellent characteristics which enable to attain both high luminance and high resolution at the same time. Also disclosed are a gas proportional counter using such a microchannel plate and an imaging device. Specifically disclosed is a microchannel plate which comprises a base body provided with a plurality of through holes (13) and having an insulating property. This microchannel plate is arranged in a gas atmosphere mainly containing an inert gas and constitutes a proportional counter. The base body has photoelectric converter portions (1a, 1b) formed at least on the inner walls of the through holes (13).
La présente invention concerne une plaque microcanal présentant d~excellentes caractéristiques permettant d~atteindre en même temps une luminance et une résolution élevées. Elle concerne également un compteur à gaz proportionnel utilisant une telle plaque microcanal et un dispositif d~imagerie. Elle concerne spécifiquement une plaque microcanal comprenant un corps de base comportant une pluralité de trous traversants (13) et présentant une propriété isolante. La plaque microcanal est disposée dans une atmosphère gazeuse contenant principalement un gaz inerte et constitue un compteur proportionnel. Le corps de base comporte des portions de conversion photoélectrique (1a, 1b) placées au moins sur les parois internes des trous traversants (13).
