The introduction of no-insulation superconducting coils is a major development in the technology of superconducting magnets. NI coils are characterized by high current density compact coils that are also very stable. The high current density in the conductor makes it important to understand the quench behavior of these coils. Modeling of quench in a REBCO pancake wound test coil shows the...

The presentation introduces actual quenches of HTS coils due to conductor degradation caused by thermal stress and electromagnetic force. Such a degradation leads to an irrecoverable thermal runaway, resulting in a catastrophic damage on the coil. NI method is a promising to protect HTS coils. The applicability of the method to pancake-winding and layer-winding is examined with experimental...

25. Finite Element Modelling of quench dynamics in 2G HTS coated conductors (25'+5')

Commercial second generation (2G) high temperature superconductor (HTS) coated conductors (CCs) possess a low normal zone propagation velocity (NZPV) in comparison with low temperature superconductor wires. One consequence of a low NZPV is that 2G HTS CCs must be over-stabilized in order to prevent the appearance of hot spots, which reduces their engineering critical current and their...

EuCARD-2 project aims to construct an HTS dipole magnet producing 5 T with an accelerator magnet level coil current density. One main ingredient is the study of quench protection. First, prototype magnets are currently being constructed for quench detection experiments, later the final delivery must be characterized. Because of the high current density and high fraction of non-stabilizing...
