This paper presents a characterization of a commercially available position‐sensitive detector of energetic ions and neutrals. The detector consists of two microchannel plates followed by a resistive position‐encoding anode. The work includes measurement of absolute efficiencies of H+, He+, and O+ ions in the energy range between 250 and 5000 eV, measurement of relative detection efficiencies as a function of particle impact angle, and a simple method for accurate measurement of the time at which a particle strikes the detector.

This paper describes a position‐sensitive detector for particles or photons which has a spatial resolution of about 15 μm. The active area is about 1.3 mm in diameter. This represents an improvement of conventional position‐sensitive detection capability by about one order of magnitude and should be useful in spectrometry, spectroscopy, and atomic collision experiments.
