Status quo of the Dresden High Magnetic Field Laboratory

At the outskirts of Dresden, Germany, a new high magnetic field laboratory for pulsed non-destructive magnetic fields up to 100 T is under construction. This user laboratory at the research center (Forschungszentrum) Rossendorf will offer access to different pulsed-field coils. Besides the ultimate goal of constructing a multi-pulse magnet reaching 100 T in a bore of 20 mm with a pulse width of about 10 ms, further self-designed high-energy coils will be provided. For thermodynamic experiments, e.g., a pulsed coil for 60 T in 40 mm and 0.5 s is planned. The necessary energy of up to 50 MJ for coil operation recently became available through a world-unique capacitor bank working at 24 kV. Coil design, coil winding, as well as coil testing have been established in house. First user-type magnets for fields up to 65 T for 10 ms in a bore of 20 mm have been tested successfully. As an outstanding feature of the newly built laboratory, the bright light of a next-door free-electron-laser facility will allow dedicated high-field infrared spectroscopy. A broad range of experimental techniques is being developed both for user and in-house research in static and pulsed magnetic fields. The new Hochfeld-Magnetlabor Dresden (HLD) is planned to open as user facility in 2007.
