Beamline Characteristics
Optical SystemThe X17 super-conducting wiggler provides high-energy x-rays with a critical energy of 22 keV. White beam or monochromatic beam can be used in the experimental hutch. Typical flux for white beam is 5 x 1014 photons/s/1%bw/0.25Å at 20keV. Monochromatic beams with energies tunable from 55 to 100 keV are provided with a Si(311) sagitally bent Laue crystal, at typical flux rate of 1011 photons/s.
Experimental Apparatus6-circle Huber diffractometer with kinematic mount, equipped with Si(220) analyzer and four sets of adjustable slits for high-energy x-ray diffraction experiments. Choice of NaI, Ge, and image plate detectors are available. Hutch can accommodate a wide range of additional experimental hardware. Experimental proposals should highlight the use of the wiggler's high energy spectrum.
Computer System Hardware & SoftwareOne PC486 with a LINUX operating system, X-Windows, SPEC, and CPLOT for operating the monochromator and experimental apparatus via CAMAC and a PCAII MCA board.
