Novel electronics for MCP imaging detectors

We describe novel electronics for processing signals from a microchannel plate detector using a resistive anode readout. High sampling-rate (MHz) Analogue-to-Digital Converters (ADCs) coupled to a Digital Signal Processor (DSP) combine to offer high spatial resolution ( 70 μ m ) , low noise ( < 0.1 count cm - 1 s - 1 ) imaging over a large ( 93 mm × 93 mm ) imaging area. new low-cost electronics form an integral part of a MCP-based system for digital autoradiography designed to image radiolabelled thin tissue slices and 1- and 2-D electrophoresis gels.
