ABSTRACT:
An electron multiplier device comprises two superposed microchannel plates. At their common interface, the angle of the axis of the channels of the plates is on the order of from 25.degree. to 30.degree. so as to increase the number of optical reflections in the channels. The more reflections, the lower the optical feedback from the output of the multiplier. At least one of the plates comprises curved channels. The curvature of the channels is such that at the entrance and the exit of the multiplier the axis enclose a small angle of at the most 10.degree. with the normals to the faces of the plates.
