Canadian Macromolecular Crystallography Facility

Overview

The scientific goal of the 08ID-1 beamline is to operate a protein crystallography beamline suitable for studying small crystals and crystals with large unit cells. The overall design of the beamline consists of white beam slits (WBS), a double crystal monochromator (DCM) with an indirectly cryo-cooled first crystal and sagittally focusing second crystal, and vertical focusing mirror (VFM). The beamline is completed with an innovative endstation and a Pilatus3 S 6M X-ray detector. The beamline controls are based on EPICS and are complemented with MxDC, a user-friendly interface developed in-house.

The source of X-rays on 08ID-1 is a small-gap undulator inserted into the storage ring (and is hence termed an "insertion device"). As its name suggests, the undulator produces a periodic magnetic field that causes the path of the orbiting electrons to undulate, resulting in an emitted X-ray beam of higher spectral brilliance than could be produced by the simpler path taken by the electrons through a bending magnet.

The beamline is equipped with a Röntec XFlash 1001 to perform X-ray spectroscopy measurements for SAD/MAD experiments as well as X-ray fluorescence (XRF) measurements for metal identification. An ISARA automounter allows remote experiments as well as onsite work.
