      Beamline Description
      High pressure diamond anvil cell research using angle or energy dispersive x-ray diffraction techniques. X17C is a superconducting wiggler beam line. x-ray diffraction data are acquired on samples under pressures up to 300 GPa in a diamond anvil cell at x-ray energies of 5-80 keV. The beam dimension is adjustable from 1 mm x 1 mm down to 0.01 mm x 0.01 mm by slits and focusing mirrors. x-ray diffraction data for polycrystalline samples in diamond cells up to 300 GPa at ambient temperature can be acquired using a dedicated system. For resistively heated polycrystalline samples in diamond cells the temperature can be up to 1100K at 100 GPa. Single-crystal x-ray diffraction can be performed at up to 100 GPa for microscopic samples below 1 micron. Ruby fluorescence spectroscopic system is available for pressure calibration. Off-line laser-heating equipment provides temperatures up to 4000K at high pressure. The sample preparation lab is equipped with two high magnification stereo microscopes and a micro drill press.
