Abstract
Some important characteristics are described of one‐ and two‐dimensional gas proportional detectors with delay line position readout which are currently in use at beam line X12B of the National Synchrotron Light Source. The importance of careful choice of geometric design parameters is emphasized with respect to position linearity and electrical stability; position resolution of 100 μm FWHM and counting rates up to several times 105 s−1 are obtained in calibration studies. Results from some recent beam‐line experiments further illustrate the excellent position resolution and linearity, and demonstrate the usefulness of these detectorsystems for small‐angle scattering, particularly in dynamic studies.Keywords
