REBCO has been regarded as one of the most promising high temperature superconductor (HTS) options mainly due to its large in-field current carrying capacity and strong substrate mechanical toughness. Thus, it may not be a surprise that the recent high expectation on compact fusion has been largely relying on REBCO conductor and magnet technologies. Despite the recent notable achievements in...

Our experience with REBCO coils comes primarily from the development of high-field double-pancake/module wound coils for NMR magnet systems. However, many of the conclusions we have reached are quite general. We focus on insulated/insulation coils with a distributed stainless-steel co-wind as the least problematic and thus more promising for our projects, although we also have some experience...

This presentation aims to provide a concise overview of the current modeling capabilities and highlight critical gaps in simulation and protection strategies for large REBCO coils. High Temperature Superconductors (HTS) are revolutionizing the design of magnetic confinement systems for nuclear fusion and beyond, offering compactness and efficiency through their ability to generate high...

Non-insulated (NI) magnets made of rare-earth barium copper oxide (REBCO) high-temperature superconducting tapes are of interest for a variety of different magnet applications, such as in the toroidal field magnets of fusion devices. One of the primary reasons for this is the potential ability for NI coils to passively protect themselves against damage during a rapid global loss of...

Erik Schnaubelt (CERN)03/07/2025, 11:55Invited Oral
This talk provides an overview of several protection concepts and simulation tools, specific to REBCO coils, that are currently under development within the TE-MPE group at CERN. Capacitive discharge and more efficient variants of the Coupling Loss Induced Quench method will be presented as promising new protection methods. While simulation tools for LTS magnets are well developed and...

Accelerator magnets based on high-temperature superconductors will be fundamental to producing a field in excess of 16 T for future HEP machines. One of the known challenges of practical conductors made with HTS materials is a slow normal zone propagation resulting from a large superconducting temperature margin in combination with a higher heat capacity compared to conventional...
