The new user facility for high magnetic fields in Dresden, Germany

Herrmannsdörfer, T.

A new facility for experiments in pulsed high magnetic fields (HLD*) is under construction at the Forschungszentrum Rossendorf (FZR) in Dresden, Germany. In order to offer a wide spectrum of experimental capabilities at HLD, pulsed field coils are planned in the parameter range 60 T, 50 mm, 1s to 100 T, 20 mm, 0.01 s for maximum field, bore, and pulse duration. These magnets will be energized by a modular 50 MJ / 24 kV / 600 kA capacitor bank. The pulsed magnets will be complemented by commercial superconducting magnets for dc fields up to 20 T. Besides many other experimental capabilities, as a unique opportunity, infrared spectroscopy in the wavelength range between 5 and 150 µm will be possible in pulsed fields by connecting the pulsed field lab with the new free-electron-lasers of the neighbouring superconducting electron linear accelerator ELBE of the FZR.
Since 1999, we have gained experience in a pilot project by building a 1.0 MJ / 10 kV / 61 T high field laboratory. Funded since 2003, we have already completed our laboratory building and machineshop. In addition, we have planned and started to assemble the 50 MJ power supply which can be partly used in 2005 and will be fully operational by 2006. First pulsed test coils have already been built and tested using a 1.44 MJ / 24 kV / 37 kA pilot power supply manufactured at FZR. Currently we are starting to order our experimental equipment. Together with the user coils, this equipment will be mainly installed and put into operation during 2006. We are planning to open the doors of our laboratory to users in 2007.

* The HLD project has been jointly submitted for funding by the Forschungszentrum Rossendorf FZR, the Leibniz Institute for Solid State and Materials Research Dresden, the Max Planck Institute for Chemical Physics of Solids, the Max Planck Institute for the Physics of Complex Systems, and the Institute for Solid State Physics of the Dresden Technical University in 1998. It is jointly funded for installation by the Federal Ministry of Education and Research of Germany and the Saxon Ministry of Science and the Fine Arts.
