Summary
This paper describes the design and characterisation of a new epoxy resin formulation intended to improve the performance of Nb₃Sn accelerator magnets for the Large Hadron Collider. The authors hypothesise that epoxy cracking and bonding failures contribute to the prolonged quench training observed in these magnets (10–25 quenches required for optimal performance). The new formulation combines dual amine curing agents, a viscosity reducer, and a coupling agent to achieve improved toughness, processability and bonding characteristics, with performance validated through a comprehensive suite of mechanical and thermal tests.
UK applicability
This research is not directly applicable to UK agricultural, soil health or nutrition practice, as it concerns materials science for particle physics infrastructure at CERN.
Key measures
Glass transition temperature (Tg), viscosity, tensile strength, compressive strength, shear strength, thermal shock resistance
Outcomes reported
The study evaluated a new high-toughness epoxy formulation designed to reduce quench training in Nb₃Sn accelerator magnets through optimised curing agents, viscosity reduction, and coupling agents. Comprehensive materials testing was conducted, including thermal shock, tensile, compressive, shear, viscosity and glass transition temperature measurements.
