The resin used for bonding and insulating superconducting magnets can be a major factor in ensuring reliable and stable operation of the completed assembly. There are many resin systems and available to magnet designers and engineers. The selection of the correct material depends on the application technique selected, the processing requirements and the end properties required of the cured...
In this talk, we will present magnet performance and quench training of LBNL Nb3Sn accelerator magnets and our experience and quests for a better epoxy for reducing quench training in Nb3Sn superconducting magnets. We will present our assessment of properties of CTD-101K, several other epoxies that have been used for superconducting magnets, and new recipes being explored at LBNL, and discuss...

The Future Circular Collider Study (FCC, hosted by CERN) explores possible designs for circular colliders addressing the post-LHC era. To reach higher energies which is...
Superconducting magnet epoxy impregnation has the unique requirement of utilizing a liquid with very specific properties at slightly elevated temperatures that transforms into a solid with low temperature property requirements. Here we test the properties of two neat resin epoxies at room and cryogenic temperatures. Tensile, compressive, fracture toughness and thermal expansion tests are...
Epoxy resins have long been a focus of superconducting 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. While a large variety of alternative thermoset resins have been...
