Abstract
An assessment will be made of two quench-protection strategies for HTS conductors, one based on dielectric insulations with enhanced thermal properties and the other on a cryovaristor technology. Three insulations are considered: ceramic powders in Formvar, sputtered ceramics, and diamond films. Both strategies make use of established databases at CeramPhysics (except for diamond films). Additional thermal measurements will be made on Formvar/powder composites, and a sputtered ceramic film on an HTS conductor will be demonstrated. Three-dimensional, transient, heat transfer modeling for the insulations will be performed by Prof. M. K. Chyu of the University of Pittsburgh. The electrical/thermal properties of a cryovaristor film will be modeled. The most favorable strategy will be identified.
