High spatial resolution position sensitive counter for use in muscle diffraction

Abstract

A position sensitive counter with high spatial resolution is described for use in low angle X-ray scattering studies from live muscles. The main sources of spatial noise are evaluated to enable the design of the counter which has a spatial resolution of 100 mu m (FWHM), an efficiency of 85% for the detection of 1.54 AA X-rays and requires a gas flow of only approximately 10 ml/day to maintain suitable operation.
