Exploring New Resin Systems for Nb3Sn Accelerator Magnets

Abstract

Epoxy resins have long been a focus of magnet design. They provide strength and stability to the superconductor, to allow coil fabrication and consistent magnet performance. They are often cited as a main contributor to magnet performance, often as a limiting factor, from epoxy cracking and energy release. New resin systems are being designed to improve magnet quench and training performance through several means. Baseline candidate resin systems are evaluated for neat resin mechanical properties as well as behavior in Nb3Sn subscale composites. This data feeds additional resin system tuning to meet the goals stated above.
