Abstract
This paper reviews and summarizes the dielectric properties of liquid and gaseous helium and nitrogen, vacuum, and solid insulation materials for practical insulation design for superconducting coils. The influence of electrode geometry on breakdown voltage is discussed, and features that require special care are pointed out. Appropriate room-temperature high-voltage testing is considered. Finally, the paper examines the implications for coil insulation design of a new class of superconductors that can operate at temperatures approaching 77 K.
Research sponsored by the Office of Fusion Energy, U.S. Department of Energy, under contract DE-AC05-84OR21400 with Martin Marietta Energy Systems, Inc.
