Vector Superconducting Magnet

VEKMAG is a Vector Superconducting Magnet instrument designed for XAS/XMCD measurements, for resonant and-off resonant soft X-ray scattering methods, as well as for time resolved ferromagnetic resonance using XMCD, in high magnetic fields and for a temperature range of 2 K - 500 K. It provides a 9T field in the beam direction, a 2T field in the horizontal plane and a 1T field in the perpendicular direction. A 1T vectorial field can be applied in all directions.

The instrument is hosted at the bending magnet beamline PM2which offers an extremely stable beam. To be able to change the polarization of the x-rays very rapidly, a hexapod vacuum chamber with six moveable legs supporting a mirror was developed. Slight changes of the leg positions can change the orientation of the first mirror and thereby the polarization of the x-ray beam in just seconds. This prototype arrangement improves the signal-to-noise ratio by a factor of more than ten.

VEKMAG has being jointly developed by Regensburg University, Free University Berlin, Ruhr University Bochum, and Helmholtz Zentrum Berlin.
