The so-called Conductor On Round Core (CORC) and the Twisted Stacked-Tape conductor (TSTC) are both the most compelling candidates for the development of high temperature superconducting (HTS) cables, both with the high current carrying capabilities required for the future development of fusion projects, with the CORC cross-sectional design being generally larger than its TSTC counterpart. In...

The shift from fossil fuel to electric based propulsion in the waterborne transport sector has been sped up by recent policies aiming to reduce the sector emissions. This trend creates highly electrified vessels, with needs for energy storage systems (ESS) to satisfy the power demand affordably and to increase the on-board grid reliability and efficiency. Initial industry efforts have been put...

Abstractโ High-temperature superconducting (HTS) tapes, represented by Rare Earth-Barium-Copper-Oxide (REBCO) conductors, are promising for high energy and high field superconducting applications. However, practical applications subject HTS conductors to various stresses and strains, including residual stresses due to thermal mismatch and tensile stresses from Lorentz forces. This can result...

Abstractโ In this work, a new topology of an inductor of axial flux synchronous machine is presented and tested. It is executed by combining superconducting (SC) bulks and six solenoids. It consists of six superconducting solenoids connected in series stuck in a non-magnetic disc and supplied by direct current. The presence of two SC bulks which by their magnetic field screening property,...

Here we report an electromagnetic-mechanical simulation model to calculate screening current, mechanical stress/strain, magnetic field, and coil voltage. We designed, fabricated, and tested a 20-turn dry-wound REBCO test coil. The coil operated in the cold bore of a 15 T background magnet, deliberately positioned off-centered to induce large screening currents. The coil was exposed to axial...

Homogenization techniques are appealing in reducing the computational cost of simulating structures with many stacked high temperature superconductor (HTS) tapes. In this contribution, the foil conductor model is extended to HTS applications with insulated conductors. The model is derived in 2-D with the Aโformulation and allows directly imposing the current in the conductors. Preliminary...

The superconducting magnet system is a key component of the tokamak fusion reactor for confining high-temperature plasma. High-temperature superconducting magnets are favored by various countries due to their larger critical temperature and critical magnetic field. When high-temperature superconducting magnets are applied to fusion devices, they will be subject to various steady-state and...

Superconductors play a crucial role in the advancement of high-field electromagnets used for particle accelerators, magnetic resonance imaging, fusion reactors, and many other high-end technological applications. Unfortunately, their performance can be compromised by thermomagnetic instabilities, wherein the interplay of rapid magnetic and heat diffusion can result in catastrophic flux jumps...

HTS coils used for high field magnets are usually made of several metal-insulated or non-insulated HTS pancakes. Quench modeling of these coils requires time-dependent simulation of current distribution inside each pancake. Partial element equivalent circuit is well-known method of modelling HTS coils, however due to large number of magnetically coupled elements, it can be time and memory...

The no-insulation (NI) coil technique has proven to be robust for realizing high-field magnets with REBCO high-temperature superconductors (HTS). While the stable operation and charging delay โ both originating from the inter-turn current transfer โ on one hand, ensure the success of NI coils, on the other hand, they limit their application scenarios. A possible solution to the charging delay...

This work presents the 3-D modelling and measurements of the sorting of a 10 cm long high-temperature superconducting bulk undulator. We use the H-ฯ formulation together with the matrix method to produce an inverse analysis of the trapped field potential of each bulk. The simulation results are then used to sort the bulks in order to reduce the field error. A factor of 1.8 error reduction was...

Various quench detection methods are under development at EPFL Swiss Plasma Center, aiming at the detection response determined solely by temperature and not affected by EM noise or mechanical strain. This can be especially useful when applied to HTS coils. Currently, the promising options are twisted-pair SQDs (essentially, co-wound insulated superconducting wire), thermocouple chains and...
