The new 20 MW high magnetic field installation at the University of Nijmegen

The University of Nijmegen is setting up a new installation for high magnet ic field research, with generous support of the Netherlands Organization fo r 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 conver ter delivering up to 40 kA at 500 V, and a cooling system. The cold water s ystem will use cooling towers with the optional use of two chillers, in com bination with a 1400 m(3) buffer, and the inlet-temperature of the cooling water to magnet coils can be kept below 15 degreesC, while allowing uninter rupted experiments at the maximum power for up to 3h/day. The laboratory wi ll have six resistive-magnet sites, and a pulsed-field-installation with a 2MJ capacitor bank and three pulsed-magnet cells. The laboratory will opera te amongst other two 33 T resistive magnets with 32mm bore; these will be c onstructed in close collaboration with the National High Magnetic Field Lab oratory in Tallahassee, FL. Design efforts have been started such that in a later phase, using the existing hybrid magnet system Nijmegen-II, even hig her fields can be generated with a newly designed high-power insert coil. d egrees 2001 Elsevier Science B.V.
