MICROCHANNEL PLATE, GAS PROPORTIONAL COUNTER AND IMAGING DEVICE

摘要

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).
