A new world-class installation for high magnetic fields


Dr. Jos A.A.J. Perenboom, High Field Magnet Laboratory, University of Nijmegen


In April of this year a first experiment at subkelvin temperatures marked the completion of the construction of a new 20 MW infrastructure to generate high magnetic fields at the High Field Magnet Laboratory in Nijmegen. The construction of the new laboratory had started with an agreement between KUN and FOM in January 1999 and was completed in four years. In this talk the layout and characteristics of the installation will be discussed, and some insight will be given in where the challenges are in generating continuous fields in the range of magnetic field strengths over 30 tesla.

In addition, in this new laboratory, and building on earlier expertise of UvA, a pulsed magnetic field installation was built, aiming at peak fields (in tens of milliseconds) of 80 tesla. One of the unique opportunities of the installation is the combination of  the 20 MW power converter and the 2 MJ capacitor bank to produce long pulses of the highest fields.

The High Field Magnet Laboratory is a large infrastructure, partially funded by FOM and EU, and is open for qualified researchers needing access to the highest magnetic fields.
