High magnetic field science is having an important impact in many disciplines, including medicine, chemistry, and condensed-matter physics. Recent accomplishments include the development of functional magnetic resonance imaging (fMRI)

at CERN, which were built in Europe, as well as those contemplated for the International Thermonuclear Experimental Reactor (ITER) , depend on magnet technology developed in the United States, as do the magnets installed in several other user facilities overseas.

Lying at the heart of much of the science done with magnetic fields today is the phenomenon of superconductivity. Investigation of superconductivity is a thriving area of materials science and condensed-matter physics, much of it now aimed at understanding how superconducting materials, especially high-critical-temperature superconductors, respond to magnetic fields.

From page 106... ...
U.S. scientists will be unable to access a wealth of science opportunities if high magnetic field instrumentation is not provided at the Spallation Neutron Source and the nation's third-generation light sources.

From page 107... ...
The limited availability of the very low temperature (<10 mK) setup in Gainesville and the maximum field at which it can operate are other constraints.

From page 108... ...
With these combined capabilities, researchers would be able to probe the dynamical properties of magnetic materials, the structure of magnetic moments in solids, and magnetic field-induced phase transitions. It should also be noted that by improving the high magnetic field instrumentation at existing neutron facilities, capabilities could be obtained that are comparable to, or exceed, those now available in Europe.

This recommendation is aimed primarily at the communities interested in high-field magnets and is motivated by the obvious advantages that might accrue to all if resources were pooled to solve common problems. The committee is openminded about how this activity should be organized, but the objective is clear: to bring together scientists and engineers from all the communities working today on magnet technology, including the magnet engineers at NHMFL, academic researchers, the magnet designers in the high-energy physics and fusion communities, commercial vendors of superconducting magnets, including NMR and MRI systems, and manufacturers of advanced materials, such as high-strength materials and superconducting wire.

From page 110... ...
Agencies supporting high-field magnetic resonance research should directly support the development of technology and instrumentation for magnetic resonance and MRI. Without improvements in ancillary equipment, such as NMR probes, resonators, MRI coils, and radiofrequency electronics, the scientific benefits of higher magnetic fields will not be fully realized by the magnetic resonance community.

CO N C L U S I O N S A N DR E C O M M E N D A T I O N S 111 investments in NMR/EPR/MRI technology could result in improvements in instrument capability that have a large, beneficial impact on the quality and quantity of the data produced by many of the scientists these agencies support. (The committee recognizes that exploitation of the opportunities offered by the development of higher-field magnets will require concomitant advances in instrumentation and technique for nearly all applications in all disciplines, but in the area of magnetic resonance the need is particularly acute.)
