The charge detector array is controlled by means of a stand-alone controller outside the vacuum envelope.

Because of the potentials involved in the analyser and also the need to supply 2kV to the microchannel plates, the control electronics must be able to float at up to 3kV from ground potential. In order to achieve this the controller is designed to act as an internet node, communicating via TCP/IP, and connected to the rest of the computer network with a fibre-optic ethernet.

The controller includes control of the microchannel plate power and bias supplies as well as supply of control voltages to the detector and collecting data from the detector for transmission over the ethernet link. The control electronics is built around a miniature credit card sized Linux computer, the iPEngine.

The control electronics was designed by the instrumentation group at the Daresbury Laboratory.
