I07 features a Pilatus 2M detector mounted on a detector positioning system (DPS). This allows it to be positioned at any distance between 0.3 and 3 metres from the sample.
Pixel size | 172 µm |
Pixel dimensions | 1679 x 1475 |
Sample-detector distance | 0.3 - 3.0 m |
The beamline has a chamber optimised for use in GIWAXS experiments. It features internal pre-sample slits and a beamstop, along with a blade directly above the sample. As the chamber can be helium filled, these combine to minimise background scatter. The chamber also has a heating stage. Alternatively, it is possible to switch the stage for a custom, user-provided stage within the chamber (subject to space constraints; please contact beamline staff if you wish to do this). There are also ports for mounting devices such as lasers and lamps.
Use of our GIWAXS chamber should give the best quality of data. Note that due to the size of the exit window, it is not possible to obtain a Q range greater than that with the detector at 40 cm, due to shadowing. It is possible to measure GIWAXS with user-provided sample environments, although these will not benefit from our internal slits and beamstop.
The GIWAXS chamber can also be used for GISAXS measurements with the detector at a greater distance.
