Central data collection facility for protein crystallography, small angle diffraction and scattering at the Daresbury Laboratory Synchrotron Radiation Source (SRS), England

An experimental workstation for protein crystallography using synchrotron X-radiation is described. Different modes of the single, bent, triangular monochromator are discussed for both the rapid collection of high Bragg resolution native crystal data and high spectral resolution (( delta lambda / lambda )<or approximately=5*10-4) optimised anomalous dispersion studies for the solution of the so-called crystallographic phase problem. An indication of the way in which the experiment can accommodate small angle work is also given.
