Instrumentation

Beamline Characteristics

Energy Range Mono Crystal or Grating Resolution (ΔE/E) Flux Spot Size (mm) Total Angular Acceptance (mrad)
6.5 – 20 keV (focused); 6.5 - 40 (unfocused) Si(111) 2.0 x 10-4 (@ 8 keV) unmeasured 0.3H x 0.3V (focused); 60H x 3V (unfocused) 3.0

Source Type
Bending magnet

Optical System
Monochromator: Si (111) channel-cut located 10 m from source. Focusing Mirror: Rhodium-plated bent cylindrical Si single crystal for 1:1 focusing at sample located 11.3 m from source.

Experimental Apparatus
Radiation hutch. 6-circle Huber 5020 diffractometer with vertical scattering geometry. Computer-controlled table for Huber. Ion chambers, Princeton Instruments CCD area detector, 8 cm 640-element Si strip detector. Bicron scintillator and two-circle analyzer stage with Ge(111) crystal analyzer also available. Beamstops with photodiodes for through measurement when using CCD. X-Z scanner fits standard well plates for transmission measurements of liquid samples. Users may design environmental chambers to suit their experiments.

Computer System Hardware & Software
Pentium class computer running Linux for beamline optics, Huber and table; Pentium-class computer running Windows for CCD; VME crate interface for beamline control and scaler data acquisition.
