The Charge Detector Array is designed to operate in vacuum. The MCP stage requires a reasonable quality vacuum in order to operate properly and the surface science experiments which provide the application for the array require ultra-high-vacuum (UHV).

The custom ASIC is mounted on a ceramic substrate, which forms the support for the circuit and also the mounting for the microchannel plates.

The ceramic module containing the ASIC and the MCPs is then mounted on a mechanical jig to hold it at the correct place at the focal plane of the analyser. The meachnical jig includes a multi-way feedthrough to take the signal and control wires for the detector through the vacuum envelope.

The picture on the left shows a module assembly ready for fitting to a VG Thermo CLAM4 Electron Energy Analyser.

The design of the mechanical assembly is due to Dave Teehan at Daresbury Laboratory.
