application (Figure 6). GA is working with UW to loan the magnet
for UW's experiment in late 2020.
GA is also exploring other possible applications. The positive
features of the HTS magnet design - stable high field, relatively
large warm bore, compact foot print, conductive cooling, ease of
mobility, rapid fringe field decay, and automated quench protection - suggest similar magnets could also be useful in a variety of
other fields. These include energy science, condensed physics,
medical devices, microwave devices, material control applications, semiconductor crystal processing, scientific instruments,
and defense applications.
-Dr. Zbigniew Piec is research scientist and Thomas W. Overton* is science editor, at General Atomics in San Diego.

pinch mirror magnets. Courtesy University of Wisconsin Madison.
The functional stability and safety of the magnet and supporting equipment, including the power supply, data acquisition,
and quench protection systems were demonstrated through 104
hours of operation at 680 A. In addition, the magnet demonstrated safe discharges and quenches from the high current and field
operating points.
