Beamline Characteristics

Energy Range Mono Crystal or Grating Resolution (ΔE/E) Flux Spot Size (mm) Total Angular Acceptance (mrad)
6 – 15.2 keV Ge(111) 6 x 10-4 ~ 1012 ph/sec (theoretical @ 10 keV, 70 mA, 2.5 GeV) 0.8H x 0.6V (focused)  

Source Type
Bending magnet

Optical System
Mirror: Platinum coated fused silica toroidal mirror for 1:1 focusing at sample located 24 meters from source; sagittal radius is 68.4 mm, meridional radius is 2100 meters; grazing angle of incidence is 5.7 mradians; mirror may be lowered away from the incident beam path; located 12 meters from the source.

Monochromator: Double flat crystal monochromator (Golovchenko type); piezoelectric driver with feedback keeps crystals in parallel alignment; crystal movement ranges from 7 deg. - 68 deg. Bragg angle; located 22.5 meters from the source. Vertical and horizontal slits located before mirror and monochromator may be positioned in 3 micron steps. A set of six attenuators can be remotely inserted into the beam after the monochromator.

Experimental Apparatus
Radiation hutch; six circle Huber diffractometer; ion chambers; Bicron scintillation detectors.

Computer System Hardware & Software
X10A is interfaced to a UNIX/PC with a DSP-6002 crate controller running SPEC data acquisition software. CPLOT is available for analysis.
