UHV Superconducting Magnet System for Soft X-ray MCD Experiments

In the framework of the ESRF upgrade program, the soft X-ray beamline UPBL7 will replace the current beamline ID08. The new beamline will be installed on port ID32 and will be equipped with a superconducting magnet system dedicated to study the electronic and magnetic properties of matter using soft X-rays from 300 up to 1500 eV. The magnet system comprises two nested UHV cold bore split-coil magnets of ±9T along the X-ray beam and ± 4T perpendicular to the X-ray beam and a variable temperature insert with a temperature range of 1.5 to 400 K. The VTI wiring will include possibilities to measure total electron yield, sample transport properties or the application of an electric field. The system will be further equipped with a UHV sample preparation facility allowing in-situ application of surface science techniques.
