132. Delamination of REBCO tapes induced by electromagnetic forces: an experimental study.

Célia Lucas Esparseil

Talk

The remarkable superconducting properties of REBCO tapes in high magnetic fields render them highly suitable for applications such as fusion magnets and particle accelerators. However, their mechanical limits under transverse tensile stresses from Lorentz forces and screening currents in high-field coils must be addressed for reliable performance. This study investigates the delamination...

4. Lessons learned from ultra high-field, high-stress REBCO coil tests

JESEOK BANG

Talk

The 'Little Big Coil (LBC)' experiments investigate key coated conductor characteristics in a high field and high stress environment by testing a REBCO coil in the bore of the NHMFL 31.1 T Bitter magnet. Indeed, LBC3 first demonstrated excessive screening current stress (SCS) resulting in wavy plastic conductor damage, while obtaining the record-high DC magnetic field of 45.5 T by generating...

41. Recent topics on ac loss characteristics of Spiral Copper-plated Striated Coated-conductor cables (SCSC cables)

Prof. Naoyuki Amemiya (Kyoto University)

Talk

The Spiral Copper-plated Striated Coated-conductor cable (SCSC cable) is our novel concept of high current cable with low ac loss, in which copper-plated multifilament (striated) coated conductors are wound spirally on a metal core in multiple layers. Whereas copper-plating allows current sharing among filaments against local defects in filaments, the spiral geometry of filaments decouples...
