Abstract
The University of Nijmegen is setting up a new installation for high magnetic field research, with generous support of the Netherlands Organization for Scientific Research. The user-facility will open its doors in summer 2002. The heart of the new installation will be a low-ripple 20 MW power converter delivering up to 40 kA at 500 V, and a cooling system. The cold water system will use cooling towers with the optional use of two chillers, in combination with a 1400 m 3 buffer, and the inlet-temperature of the cooling water to magnet coils can be kept below 15°C, while allowing uninterrupted experiments at the maximum power for up to 3 h/day. The laboratory will have six resistive-magnet sites, and a pulsed-field-installation with a 2 MJ capacitor bank and three pulsed-magnet cells. The laboratory will operate amongst other two 33 T resistive magnets with 32 mm bore; these will be constructed in close collaboration with the National High Magnetic Field Laboratory in Tallahassee, FL. Design efforts have been started such that in a later phase, using the existing hybrid magnet system Nijmegen-II, even higher fields can be generated with a newly designed high-power insert coil.
