Description
A one dimensional detector array using MCP technology in conjunction
with a custom ASIC is presented. The detector chip features 768
pixels, each 3mm in length on a pitch of 25um, giving a length in
the dispersive direction of 19.2 mm. Each pixel is furnished with a
pre-amplifier and discriminator coupled to a 16-bit counter. The chip
and MCP are mounted on a ceramic and stainless steel assembly that
replaces the conventional channeltron in a CLAM4 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.
