Abstract

A station designed to speed up the collection of integral intensity data from protein and virus crystals is constructed on the synchrotron radiation beam of the VEPP-3 storage ring. A flat triangular Si crystal cut at 8° relative to the (111) plane is used to monochromatize the radiation. A conventional Arndt-Wonacott rotation camera is used to collect structural information. The station also includes an optical bench which can turn about the axis coinciding with that of the monochromator, and a set of slits to cut the background and to form the beam. The ionization chamber serves to adjust the monochromator and to monitor the beam. Numerical results of first measurements from protein crystals as well as plans for future work are presented.
