Station 10.1 has been designed to match the requirements for a world class beamline of Structural Genomics and Proteomics projects. The NWSGC was funded jointly by the UK Research Councils (BBSRC, EPSRC and MRC) to build a new MAD beamline at the SRS on a new high field Multipole Wiggler source.

Functional Description

The station can offer rapidly tunable monochromatic X-ray beam between 0.9Å wavelength and 2.4 Å wavelength combined with automated sample changer and fluorescence detector for EXAFS investigations.

Technical Description

In order to meet the requirements of speed and tuneability necessary for this project a new 2.4 Tesla 10 pole wiggler beamline (MPW10) has been developed by Daresbury project team staff. The optical arrangement is characterised by a Rh coated collimating mirror, a double crystal Si(III) monochromator with horizontal saggital focusing system, and finally a second Rh coated mirror for vertical focusing.
The monochromatic beam is optimised through a 200 by 200 micron2 collimator. The double crystal monochromator does guarantee rapid tunability and high energy resolution allowing data to be collected from small, weakly diffracting crystals over a wide range of wavelengths. It will be dedicated to MAD/SAD techniques, operating in the 4 to 14 keV photon energy range, or 2.5 to 0.9 range.
The station is equipped with MAR automated sample changer and semi-automatic crystal alignment, with a 2Θmax of 30º at maximum tilt and closest detector to crystal distance. Up to 19 samples can be loaded at once on the robot considerably reducing the time needed to change samples. The station is currently equipped with the latest version of a CCD165 detector (2.5 secs readout).
The station is equipped with an Oxford Cryojet for data collection at temperatures down to 100K.


C-TRAIN Fluorescence detector

Proposed Development

This will be soon replaced by the bigger MAR 225CCD (1 sec readout).


At a wavelength of 1.379 A (Cu K edge) with 250 mA users should expect a reading of 50K on ion chamber 2 and 20K on ion chamber 2 with slit apertures 0.6(h)x0.3(v) and 0.2(h)x0.17(v) respectively.
