High field magnet facilities and projects at the Forschungszentrum Karlsruhe

Three experimental facilities JUMBO, HOMER I, and MTA exist in the high field magnet group of the Institute for Technical Physics for investigations in high magnetic fields up to 20 T. All setups are based on advanced superconducting mae;nets. The facility Homer II is presently under construction in order to achieve magnetic fields up to 25 T. Our current projects focus on the development of solenoids for NMR (nuclear magnetic resonance) spectrometers. Together with our industrial partner Bruker Analytik GmbH, we introduced in 1991 the world's first 750 MHz (17.6 T) and in 1995 the world's first 800 MHz NMR spectrometer (18.8 T) on the market. At present a prototype magnet system for a 900 MHz spectrometer (21.1 T) is in progress. To further improve the resolution of the NMR spectrometers, a national project for the development of a 1000 MHz spectrometer (23.5 T) has been started together with Bruker Analytik GmbH and Vacuum-schmelze GmbH.
