VEKMAG - a vector magnet for BESSY II

VEKMAG is a Vector Superconducting Magnet station which is being jointly developed by Regensburg University, Free University Berlin, Ruhr University Bochum, and Helmholtz Zentrum Berlin. The instrument will be installed at Helmholtz Zentrum Berlin, in the experimental hall of the synchrotron facility BESSY II.

The instrument is 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 will provide 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 envisaged home beamline is located at the PM2 bending magnet at BESSY II. The station is expected to be commissioned in spring 2014. The VEKMAG end station is funded by the BMBF, and the PM2 beamline by HZB.
