A One-Meter-Diameter, Ac Superconducting Coil and Fiberglass Cryostat for an Electromagnetic Geophysical Exploration System
The design, fabrication, and testing of a 1-m-diameter, ac superconducting coil for a superconducting geophysical exploration device have been completed. A large fiberglass cryostat with a novel high-electrical-Q superinsulation system was built and used for testing the coil. Calorimetric measurements of the ac superconductor loss have been made at three frequencies, and sensitivity tests of the prospecting capability of the coil have been made.
