Abstract
A new macromolecular crystallographic facility developed by The General Medicine and Cancer Institutes Collaborative Access Team (GM/CA-CAT) at the Advanced Photon Source (APS) is a part of the Biosciences Division (BIO), Argonne National Laboratory (ANL). The facility consists of three beamlines: two lines based on the first "hard" dual canted undulators and one bending magnet beamline [1]. Several compact collimator systems have been developed for the purpose of background reduction in macromolecular crystallography experiments. The apparatus consists of a tube collimator, pinhole and kinematics mount. This paper will present a series of compact collimator designs and crystallographic applications based on experimental requirements [2]. We also describe the magnet-based kinematic mounting structures [3] developed as a collimator holder.
