Since more than 20 years the high-field laboratory (HFL) of the Institute for Technical Physics at the Forschungszentrum Karlsruhe develops, constructs and operates superconducting high-field magnets. During this period we achieved, inter alia, the world record of 20.1 Tesla for a superconducting magnet system (HOMER 1, 1987) and introduced the world's first commercial 750 MHz, 800 MHz and 900 MHz NMR-spectrometer, together with our industrial partner Bruker Biospin.
Current tasks of the HFL-group is the construction of the HOMER II test facility with magnetic fields up to 25 Tesla and a national BMBF-project for the development of a 1000 MHz NMR-spectrometer (23.5 Tesla) together with Bruker Biospin.
Two experimental facilities, JUMBO (max. 15 Tesla) and HOMER I (max.
20.1 Tesla) exist in the high field laboratory for the required investigations
in high magnetic fields. The first construction stage of the third facility,
HOMER II, with a magnetic field of 20 Tesla in a bore of 180 mm diameter
will start up soon. All setups, based on advanced superconducting magnets,
are presented in this contribution.
