title: Soft x-ray appearance potential spectroscopy with a channelplate detector.
abstract: A soft x-ray appearance potential spectrometer using a channelplate detector is described and evaluated. This detector is much more sensitive than the metal photocathode in common usage and provides useful SXAPS spectra at primary electron currents of less than 10 microA. Operation of the detector at high x-ray fluxes is limited by saturation effects which can be minimized by the proper choice of channelplate and geometry.
