In high field applications, the HTS coils are commonly impregnated with epoxy resins for insulation and mechanical reinforcement to against the huge Lorentz forces. Till now, many of the epoxy impregnated ReBCO based HTS coils show some degree of performance degradation (Jc) due to thermal stress during cool down, electromagnetic stress during operation or any other reasons. It remains a...
Quench and protection in magnets wound with coated conductors is of great interest for many applications, including those of high energy physics accelerators. The relatively large slow normal zone propagation and large MQE of coated conductors and the potential of burn out in well insulated coils has led to an interest in non-insulation coils. A stability of block type dipole magnets wound...
BOnding eXperiments (BOX) are a novel, affordable and fast benchmarking solution aiming to reproduce specific mechanisms of training and performance limitations in Nb3Sn and Nb-Ti superconducting magnets. The BOX samples are tested at the University of Twente at 4.2 K within a solenoidal background field with sufficiently high magnetic forces. Following conventional manufacturing processes,...
The performance of accelerator magnets strongly relies on electrical and mechanical robustness of their components. With an increase of the energy, future accelerators will have to withstand integral doses around 35 MGy or higher during their lifecycle. Initially developed for the components of the D1 separation dipole magnet, designed and manufactured by KEK and part of the HL-LHC Project,...
