For dc fields (constant field at least during several minutes) , available fields must be higher than 21 T, that is, beyond values reached for commercially available magnets, while pulsed fields must be operated with capacitor banks having stored energies of more than 2 MJ.

is the steady field com ponent of the National Key Science and Technology Basic Establishment Project for high-magnetic-field facilities and is funded by the National Development and Reform Commission. The principal objectives of SHMFF are to build a 40 T hybrid magnet, a series of high-power resistive magnets for multiple uses, including a resis tive high-homogeneity magnet for NMR, and superconducting magnets.

Activities include study of the origin of the magnetism in magnetic materials and the mechanisms underlying magnetically induced properties. Interesting phe nomena observed at high fields and high pressures are studied using cyclotron resonance, far-infrared and millimeter-wave spectroscopy, magneto-optical spec troscopy, Faraday rotation, magnetization, and transport measurements.

is part of the Helmholtz-Zentrum Dresden-Rossendorf and in 2006 the building and the construction of the new laboratory were finished, making the HLD now the largest pulsed field laboratory in Europe, with five measuring stations for pulsed magnets. The laboratory features an unprecedented 50 MJ capacitor bank power supply that energizes its magnets with a record field of 94.2 T, achieved in early 2012.

From page 214... ...
Tallahassee has a very strong magnet technology program that develops special magnets for external facilities (split coil, three-dimensional rotating field, a 25 T hybrid for the Helmholtz Zentrum Berlin to work with a neutron source) and new magnets for its own facility (high-homogeneity magnets and series-connected hybrid magnets)
