Abstract :
We describe the operation of microchannel plates (MCPs) with 3.2 μ m diameter channels as photon counting detectors of soft X-rays. Gain and temporal resolution measurements are compared with theoretical scaling laws for channel diameter. A minimum pulse width of 264 ps is observed for a two stage multiplier at a total bias voltage of ∼ 1930 V .
