BLADE delivers soft X-ray beam in the energy range from 0.4 to 2 keV. The research focuses on the magnetisation and the magnetic structure of novel nanostructured systems. These magnetic properties can be probed thanks to high dichroic effects in the soft X-ray region. The dichroic effect can be studied both in absorption and scattering experiments.
Two APPLE II undulators produce photons with arbitrary linear or circular polarisation. A high energy resolution is achieved using a plane grating monochromator. For increasing the sensitivity of dichroism measurements, a fast polarisation switching and a fast energy scanning will be implemented.
On the scattering branch, there is a soft X-ray diffractometer, RASOR, which consists of a three-circle diffractometer with a polarisation analyser. The concept is built around a Janis helium cryostat allowing soft x-ray reflectivity and diffraction from samples temperatures down to 12 K. For further information and enquiries about experiments using RASOR end-station, please contact Paul Steadman.
On the absorption branch, a high field magnet and an electromagnet can be used for performing magnetic dichroism experiments.
For the high field magnet, the magnetic field is supplied by a superconducting split-pair coil with a uni-axial magnetic field of 14 T along the incident beam direction. Sample can be cooled by variable temperature inserts currently down to 3 K.
The electromagnet provides a field of up to 1.9 T along the beam direction with a cryostat that cools the sample down to 15 K. The cryostat, and therefore the sample, can be rotated around the vertical axis so that the sample normal can be changed by +/- 90 degrees relative to the incident beam.
For further information and enquiries about experiments using either the high field magnet or electromagnet end-station, please contact Peter Bencok.
