Bending magnet

Optical System
Mirror System: Water-cooled silicon carbide beam extraction; beam is steered and focused by a combination of ellipsoidal and planar mirrors. Beam is extracted through 1 cm diameter (clear view), ~0.35 mm thick wedged CVD diamond window.

Experimental Apparatus
Cryostats available to user groups having full expertise at operating lHe cooled optical dewar systems. Limited support from beamline staff.

Computer System Hardware & Software
Hardware: Windows PC
OS: Windows XP
Aquisition: Bruker OPUS
