Abstract
A sandwich plate is a novel type of high-gain electron multiplier formed by bonding, in permanent contact, three standard (channel length-to-diameter ratio L/D=40:1) image-intensifier multichannel plates. This geometry has the advantage of mechanical and electrical simplicity when compared with conventional multiplate stacks. An evaluation of sandwich plates for X-ray photon counting is presented. Sandwich plate gain, gain uniformity, pulse height FWHM, dark noise, high-count-rate operation, and X-ray quantum efficiency are compared with previous measurements made with conventional two-stage MCP (microchannel plate) multipliers.Keywords
