Optical System
The X26C beamline optics consist of a channel-cut Si(111) crystal monochromator followed by a doubly focusing toroidal mirror.

Experimental Apparatus
The X26C endstation consists of a Crystal Logic diffractometer equipped with a mini-kappa goniometer, an ADSC Quantum-4 CCD x-ray area detector, and an Oxford CryoSystems 600 series cryostream. The diffractometer is equipped with a micro-spectrophotometer for the concurrent measurement of UV and visible absorption spectra with x-ray diffraction of macromolecular crystals.

Computer System Hardware & Software
Networked array of Linux PCs. CBASS data collection software, HKL2000 data analysis software.
