Filed: 1985-04-16
Abstract: PURPOSE:To achieve high speed gating by making the capacitance between a photoelectric face and a transparent conductive film sufficiently higher than that between the photoelectric face and an acceleration electrode. CONSTITUTION:Assuming the points 2, 4, 8a will correspond to random points on a transparent conductive film 2, photoelectric face 4 and the photoelectric input face 4 of a microchannel plate 8, R is the resistance between a random point on said face 4 and the transparent conductive film 2, C1 is capacitance between the random point on said face 4 and the transparent film 2 and C2 is the capacitance between a random point on said face 4 and a random point on the photoelectric face 4 of the input face 8a of microchannel plate, C1>>C2 is satisfied.
