Instrumentation

Beamline Characteristics

Energy Range Mono Crystal or Grating Resolution (ΔE/E) Flux Spot Size (mm) Total Angular Acceptance (mrad)
14 - 100 keV (White Beam) White Beam 500 eV 1014 ph/sec/0.1%bw/mm2 1H x 1V  

Source Type
7-pole superconducting wiggler, 4.2T, 17.4 cm period

Optical System
Filters: Beamline contains 0.391 mm of graphite filters, .500 mm silicon filter, and 2.0 mm of beryllium windows.

Apertures: Beamline apertures located 19 meters from the source control the vertical and horizontal source size available to the monochromator crystals.

Experimental Apparatus
Large-volume (~1 cu mm) multi-anvil press in either cubic or octahedral mode, providing pressures up to 29 GPa and temperatures up to 2000 K. Detectors include (1) a single-element solid-state Ge detector; (2) a 13 element solid-state Ge detector, of which 4 are used; (3) x-ray imaging via a YAG crystal, 10x magnifier, and CCD and video cameras; (4) Bruker CCD x-ray camera, and (5) TIP (translating imaging plate). Non-hydrostatic deformation and ultrasonic interferometric measurements are each supported in conjunction with the above high pressure and temperature apparatus.

Computer System Hardware & Software
VME crate controlled by a Windows 2000 server and 4 Windows XP workstations, all using EPICS. DAT and CVLT tape backups, one of each on the server and the control workstation. An HP 4MP+PS LaserJet printer and an HP C1700 PS color inkjet printer are available for beamline use.
