摘要

MicroChannel plate detectors with cross strip anodes have demonstrated excellent performance characteristics, their resolution has reached the 6-10 μm scale (the typical size of pores in a microchannel plate) and the imaging non-linearities are small. Working at much lower gain (～5× 10~5) than many other devices, the cross strip readout has many other advantages, low complexity, robustness, compactness and the ability to fit many formats. We have now implemented cross strip detectors in several formats including, 40mm open face (UV/particle) and 18mm sealed tube (optical). These have been combined with a new signal processing technique which allows for high counting rates exceeding 5 MHz with high spatial resolution (<20 μm FWHM). The imaging performance is dependent on optimization of firmware algorithms that are used to calculate event position centroids. With new FPGA designs and implementation considerable flexibility is gained, allowing the fidelity of the imaging readout to be progressively tuned for maximal performance.
