Source Type Bending magnet Optical System White Beam Mode: Slit-defined white radiation; capability of introducing various absorbers into beam path to modify spectral distribution.
Monochromator Mode: Constant offset double flat crystal (Golovchenko type) monochromator; first crystal is water-cooled; operates in the atmosphere; operates in tandem with multiple crystal topography camera downstream of monochromator; easily positioned in and out of beam path; located inside radiation hutch 21 meters from the source.
Focused and Monochromated: Cylindrically cut, rhodium coated, aluminum mirror mounted on a bender provides horizontal and vertical focusing. Si(111) installed in the hutch provides an ~1% bandpass. Experimental Apparatus Radiation hutch; five circle Huber goniometer with computer controlled robotic detector arm for positioning X-ray detectors; environmental chamber with beryllium exit and entrance windows; chamber mounts in eulerian cradle of white beam camera, remote manipulators, furnace, deformation stage; scintillation detectors; real-time X-ray television system; dark-room for development of X-ray films; Surface spectrometer installed in hutch. Computer System Hardware & Software Sun Ulta 5, Solaris 7 using SPEC for motor software.
