      Beamline Description
      High-resolution and single-crystal and powder scattering at 30 to 90 keV, high pressure physics, geology, and materials science using diamond anvil cell and microbeam x-ray diffraction. The X17 4.2T super-conducting wiggler produces high-energy x-rays with a critical energy of 22 keV. White beam or monochromatic beam can be used in the experimental hutches. Typical flux for white beam is 5x1014 photons/s/1%bw/0.25A at 20keV. In the monochromatic mode, two double crystal monochromators provides 30 and 80 keV x-rays. Use of specialized diamond anvil cell with laser heating is available with prior arrangement.
