... Particle accelerators and detectors, and devices for generation and control of hot hydrogen plasmas, require enormous magnets, with stringent demands on field geometries as well as requirements for the highest practical field strengths. In the United States, design and development of such magnets have largely been carried out at laboratories supported by the Department of Energy (DOE)

... High fields for the bending magnets are necessary to achieve the highest possible beam energies for a given accelerator radius. Although the magnetic field strengths of superconducting magnets for high energy and nuclear physics applications do not approach the present level of labo ratory research magnets, i.e., 1 GHz NMR, they do require mostly nonsolenoidal geometry to be useful for charged-particle beam bending (dipoles)

... The experiment is designed to convert axions into microwave photons and would be sensitive to axions with a mass in the range of 2 to 20 meV. Planned upgrades to this experiment, which should greatly increase sensitivity, do not involve stronger magnetic fields but rather involve improvements in the design of the microwave detectors and lowering of the temperature of the microwave cavity, by means of a dilution refrigeration system.

... Radiotherapy Using Charged Particles Charged particles have been used for radiotherapy since the first proposal of Wilson at MIT in the 1940s and the implementation at Lawrence Berkeley National Laboratory at about the same time. The reason high magnetic field technologies are relevant to this health science program is that magnetic fields are used in the source beams of charged particles as well as in steering the beams to the patient.
