Beamline Characteristics

Energy Range Mono Crystal or Grating Resolution (ΔE/E) Flux Spot Size (mm) Total Angular Acceptance (mrad)
~6 – 23 keV Si(111) 2.0 x 10-4 ~1.5 x 1013 ph/sec/0.1%bw/mrad 0.5H x 0.1V (max) 3

Source Type
Bending magnet

Optical System
Monochromator: Si(111) channel cut monochromator.

Mirror: Oxford Danfysik toroidal focusing mirror.

Experimental Apparatus
The end station includes: a CrystalLogic single axis diffractometer, a Kappa goniometer head, and an ADSC 210 CCD detector constitute the heart of the experimental setup. An ALS Automated Sample Changer, an Oxford Cryosystem series 700 sample conditioner, and an SZX 12 Olympus microscope complete the sample environment.

Computer System Hardware & Software
The control of the optical components and the experiment in itself is carried out on a PC workstation running Debian Linux. The beamline control system is implemented in VME with software based on EPICS. The experiment/data collection is controlled through a Blu-Ice-like graphical user interface. Open source data analysis packages are available for data manipulation and refinement.
