Paper Abstract

Imaging detectors utilising microchannel plates with electronic position readouts, in general, require the output charge cloud to have a well defined size and form. We describe an experimental technique to measure this spatial distribution. We present measurements of the distribution under a wide variety of operating regimes and discuss the importance of each of the detector operating parameters. We show that the radial charge distribution has a general form which can be described by the sum of two exponentials.
