Instrumentation

Beamline Characteristics

Energy Range Mono Crystal or Grating Resolution (ΔE/E) Flux Spot Size (mm) Total Angular Acceptance (mrad)
~3.8 - 24 keV White Beam or Si(111) 1 x 10-4 ~5 x 109 ph/sec 0.01H x 0.003V ~10 rad H x 10 rad V

Source Type
Mini-Gap Undulator (MGU)

Optical System
0 meters: Source – MGU

11 meters: Motorized vertical and horizontal slits

20 meters: Monochromator chamber (can be manually lowered for white-beam operation) consisting of in order from upstream:
i) 254 m thick Be window
ii) 2 mm or 4 mm vertical slit ladder with or without graphite filter
iii) Si(111) double-crystal monochromator,
iv) Water-cooled copper white beam stop

Inside X13B Hutch:

24.5 meters: 254 m Be window

25.5 meters: Refractive optics or KB x-ray micro-focusing mirrors. The KB mirrors are 10 cm long vertical and horizontal differentially gold-coated at 3.8 mrad fixed incidence angle. Working distance ~ 23 cm

Experimental Apparatus
Sample goniometer and detector arm. Detectors consist of Amptek energy-dispersive detectors, Bicrons, silicon photodiodes.

Computer System Hardware & Software
VME (non GPIB or serial), and PC interfaced serial and GPIB systems. EPICS (running on the Motorola VME CPU and soft-PC ). SPEC user interface
Frame grabber allowing experimental visualization. Windows and Linux operating systems.
