Abstract

We have implemented cross strip readout microchannel plate detectors in a 40mm diameter active area format, open face (UV/particle) configuration. These have been tested with a field programmable gate array based parallel channel electronics for event encoding which can process high input event rates (> 5 MHz) with high spatial resolution. Using small pore MCPs (6μm) operated in a pair, we achieved spatial resolution of < 20μm FHWM at MCP gain of 1x10⁶ e^- per event. Future large aperture UV missions require detectors to have large formats (> 100 mm) with high event rate throughput (~ MHz) while retaining high spatial resolution. We will discuss our plans to scale our 47 mm square anodes to 100 mm and our ideas for the next front end ASIC that combines a state-of-the-art, fast charge sensitive amplifier with fast sampling analog storage and built in ADCs.
