Developments at the High Field Magnet Laboratory in Nijmegen

The High Field Magnet Laboratory at the Radboud University Nijmegen is rapidly expanding its capabilities. The developments encompass both organizational changes and new possibilities for research. The organization of the HFML was strengthened as a consequence of stronger participation of the Foundation for Fundamental Research on Matter (FOM), and an increase of the core-funding. This change makes that HFML is now considered on a national level as large research facility that operates at an international scale. At the same time work is underway to build new and powerful magnets, and provide electromagnetic radiation for magneto-spectroscopic studies.
Electromagnetic radiation in the infrared and far-infrared spectrum will soon be available in the HFML with wavelengths between 3 μm and 1.5 mm, produced by the ‘FELIX’ facility, comprising the long-wavelength free electron laser ‘FLARE’ that in September 2011 produced its first light and the free electron lasers that have been moved from Rijnhuizen to Nijmegen. In magnet technology great strides are made to make magnets available for the user community with unprecedented performance: late in 2012 we hope to commission a new all-resistive magnet system that will generate a steady magnetic field as high as 38 T, by fully exploiting the maximum power of the installation, i.e. 20 MW, and using all available improvements in the design and construction of ‘Florida-Bitter’ resistive magnets. We are also well underway with the design of a 45 T hybrid magnet system, using Nb3Sn superconductors and wind-and-react Cable-in-Conduit technology.

Part of this work was supported by the Dutch Foundation for Fundamental Research on Matter (FOM) and the Netherlands Organisation for Scientific Research (NWO), and has benefitted from the European FP7 programs EuroMagNET (contract no 228043) and EMFL (contract no 26211). Also the cooperation is acknowledged of our colleagues at the National High Magnetic Field Laboratory in Tallahassee FL, M. Bird and I. Dixon.
