From page 1... ...
A magnet is "high field" if its field strength is great enough to test the limits of the mechanical and/or the electromagnetic properties of the materials from which it is built. High-field magnets have been -- and continue to be -- used for research in many scientific disciplines, including medicine, chemistry, and condensed-matter physics; they are also enabling for fields such as plasma science and high-energy physics.

High magnetic field science and technology are thriving in the United States today, and the prospects are bright for future gains from high-field research. Recent accomplishments include the development of functional magnetic resonance imaging (MRI)

From page 3... ...
Finally, Europe is far ahead of the United States in equipping its synchrotron light sources and neutron scattering centers with instruments for studying the x-ray- and neutron-scattering properties of materials in high magnetic fields. It also worth noting that several key facilities in Japan have made important contributions to the development of the technologies required for the generation of the highest steady-state and pulsed magnetic fields.

From page 4... ...
The United States should maintain a national laboratory that gives its scientific community access to magnets operating at the highest possible fields. A national high-field magnet facility is essential to the vitality of many impor tant scientific disciplines.

From page 5... ...
This gap in capability is unfortunate, because scattering experiments provide a powerful means for elucidating atomic and magnetic structure, as well as for determining the nature of the spatial and dynamical correlations in materials. Development of new high-field capabilities at x-ray- and neutron-scattering centers in the United States could have an enormous scientific impact.

From page 6... ...
While federal funding for the application of existing tech nology and methods to specific scientific problems has generally been good, federal funding for the development of novel technology and methodology has been poor. Magnetic resonance and MRI instrument manufacturers have done a good job of advancing the supporting technologies for these techniques when commercial markets for their products justified their doing so.
