The National High Magnetic Field Laboratory

The National High Magnetic Field Laboratory (NHMFL) was established in 1990 , on the basis of a collaboration between Florida State University (FSU), t he University of Florida (UF) and Los Alamos National Laboratory (LANL). Th e main campus for the NHMFL is located in Tallahassee, Florida, and its gen eral purpose DC magnetic field facility is described in this paper. The pul sed field facility of the NHMFL is located at LANL in New Mexico; while the high BIT (magnetic field/temperature) facility and the magnetic resonance imaging/spectroscopy (MRI/S) activities of the laboratory are at UF in Gain esville. The NHMFL maintains at its Tallahassee user facilities the most po werful infrastructure in the world to energize resistive magnets: 36 MW con tinuously and 40 MW for up to an hour. Continuous magnetic fields from 20 T in a 195 mm bore up to 45 T in 32 mm are available. The infrastructure for the research supported includes magneto-optics (ultraviolet through far in frared), microwave conductivity, millimeter wave spectroscopy, magnetizatio n, specific heat, thermal and electrical transport, tow-to-medium resolutio n NMR, EMR, materials processing, and the dependence of optical, transport, and magnetic properties on field orientation, pressure (ambient to 15 GPa) , and temperatures from 20mK to 800 K.
