BioXAS Sector

BioXAS is a newly commissioned beamline sector at the Canadian Light Source consisting of three beamlines. The wiggler beamlines, BioXAS-Main and BioXAS-Side, are dedicated to X-ray Absorption Spectroscopy (XAS). The third, undulator beamline, BioXAS-Imaging, is a multi-resolution X-ray Fluorescence Imaging beamline. The BioXAS insertion devices occupy the same straight section of the storage ring but in a chicaned configuration to allow the beamlines to be operated independently.

The BioXAS-Imaging beamline is a hard X-ray fluorescence imaging beamline with two spatial resolution modes currently in operation. The beamline has a spectral energy range between 5 to 21 keV.
