A ''Sandwich'' plate is a new type of high gain electron multiplier formed by bonding in permanent contact, three standard (channel length-to-diameter ratio L/D=40:1) image intensifiers MCPs. Simpler to produce than a curved-channel MCP, the Sandwich geometry has advantages of mechanical and electrical simplicity when compared with conventional multi-plate stacks. The authors present an evaluation of Sandwich plates for X-ray photon counting. 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 multipliers.
