Title: Wind-and-React Magnet Insulation with Low Radiation-Induced Outgassing
Agency: DOE
Contract: DE-FG02-06ER84456
Award Amount: $649,977.00


Superconductors such as Nb3Sn and MgB2 are being considered for use in several government and commercial magnet systems. These materials require high-temperature reaction processes at temperatures on the order of 600 to 700°C. Electrical insulation materials that can withstand the high-temperature process could allow the superconductor and insulation to be co-processed at elevated temperatures, thereby enabling more efficient magnet fabrication and reduced manufacturing costs. This project will develop ceramic-based insulation materials for direct application onto superconducting wires prior to heat treatment. Other benefits of the technology include high dielectric strengths, good mechanical performance, and resistance to radiation. Phase I involved resin formulation and processing, application process development, and electrical, mechanical, and thermal characterization of the insulation material. A process for applying thin, ceramic-based electrical insulation directly onto continuous lengths of wire was demonstrated. An experiment to assess the irradiation-induced gas evolution of the insulation materials was designed. Phase II will continue the development and optimization of the insulation materials and processes, and a cryogenic dewar system will be designed and fabricated for use in a low-temperature irradiation study. The process will be scaled-up for production, prototype coils will be fabricated, and the insulation materials will be irradiation tested at an accelerator facility. Commercial Applications and Other Benefits as described by the awardee: In addition to supporting the U.S. high energy physics programs, the insulation systems should be useful in the production of next-generation MRI magnets, as well as superconducting motors, generators, and transformers. These materials also should have applications in oil and gas recovery and nuclear power generation.
