โœฆ Synopsis

Recent advances in basic microchannel plate detector technology include new photocathodes such as diamond and GaN with high UV efficiency (up to >50%), silicon-based microchannel plates with low fixed pattern noise and background event rates less than 0.02 events cm ร€2 s ร€1 . In combination with cross-strip photon counting readouts with spatial resolutions of o5 mm at low gain (4 ร‚ 10 5 ) these advances offer considerable performance improvements in future astronomical instruments.

Imaging microchannel plate (MCP) detectors with cross strip (XS) readout anodes require centroiding algorithms to determine the location of the amplified charge cloud from the incident radiation, be it photon or particle. We have developed a massively parallel XS readout electronic system that emplo
