Polycapillary X-ray optics for macromolecular crystallography

a collimating optic with a linear capture angle of 0.15 rad, 12.5J..Lm channel size, and output area of 3.1 em was placed into a standard Bragg-Bretano diffractometer.Capillary optics provide even larger signal gains for very small samples.More than an order of magnitude signal increase was achieved for a 0.3 mm Lysosyme crystal by employing an optic with a 0.1 rad capture angle and 5 mm output diameter.This paper will present a review of the broad range of applications of capillary optics to diffraction systems.
