Microchannel array plates (MCPs) in which the channels are curved to inhibit ion-feedback, in an identical manner to that employed in a conventional channel electron multiplier, have been fabricated and their performance characteristics have been evaluated. These devices represent a major advance in MCP technology since a single curved-channel MCP can be operated stably at high gain in the pulse-counting mode. Gains of greater than 10/sup 6/ electrons pulse/sup -1/ have been obtained at applied potentials of the order of 2000 V with maximum count-rate capabilities exceeding 10/sup 5/ counts mm/sup -2/s/sup -1/ and lifetimes exceeding 2.5 x 10/sup 11/ counts mm/sup -2/.
