X12-C Characteristics    
Beamline X1C-C features a Si(111) channel-cut crystal monochromator with the resolution and control suitable for Multiwavelength Anomalous Diffraction (MAD) measurements on macromolecular crystals. The beam is focused by a toroidal mirror and collimated by diffractometer slits down to a minimal spot size of 0.1 mm. Data collection is performed on our new ADSC Q210 diffractometer system which was purchased in 2005 with funds provided to BNL Biology and the NSLS by the DOE Office of Biological and Environmental Research.  
Monochromator Si(111)
Energy Range 5-20 keV
E-Resolution 8x10-4 (5eV)
Native Focus 0.3 x 0.5 mm
Spot Diameter 0.1 - 0.5 mm
Flux at 1Å 2x1010 ph/s



The new ADSC Q210 CCD detector has a square active area of 210 mm sides, achieves readouts in 1s, and can be translated vertically.

Xtals are mounted on a mini-kappa head and are rotated on a high-speed omega air bearing drive. A motorized tripodic platform serves to center and orient xtal remotely.

Diffractometer and beamline are conveniently controllled from the user desk through a suite of graphically controlled programs (CBASS) that incorporates the powerful PXdb experiment tracking data base.
