A one-dimensional detector array using MCP technology in conjunction with a custom ASIC is presented. The ASIC features 768 pixels, each 3 mm in length on a pitch of 25 μm, giving a length in the dispersive direction of 19.2 mm. The chip and MCP are mounted on a ceramic and stainless steel assembly that replaces the conventional channeltron in an electron energy analyser. Results are presented showing key aspects of the detector, including the yield of the chip at wafer stage, the vacuum compatibility of the system, the speed of readout, uniformity of response and maximum count rate.
