Abstract
A prototype 40-mm-diameter proximity-focused microchannel-plate intensifier intended for photon-counting applications in both ground-based and space astronomy is described. The intensifier described is a sealed-window device and is also well suited to open-window ultraviolet applications in space astronomy. The tube makes use of a combination of an unfilmed curved-channel plate (C-plate), to prevent ion feedback, and a single straight-channel plate, aligned to prevent optical feedback. The tube has excellent cosmetic quality and shows a counting efficiency superior to that of filmed plate devices reported previously, giving an overall detective quantum efficiency at least equal to that of the best four-stage magnetically focussed intensifiers.
