Speaker: Danko van der Laan, Advanced Conductor Technologies and University of Colorado, Boulder Colorado, USA Abstract: Advanced Conductor Technologies has been developing Conductor on Round Core (CORC) cables for high-current power transmission and high-field magnet applications during the past three years. CORC cables are wound from high-temperature superconducting REBCO tapes and have shown superior performance with respect to cable flexibility and mechanical strength. The current status of CORC cables and its relevance to applications at CERN will be presented. High operating currents in liquid nitrogen and helium gas make CORC cables suitable candidates for current feeders and bus bars. A clear path to develop high-current and high-current density CORC magnet cables has been identified, raising the engineering current density of CORC cables at 4.2 K and 20 T above 600 A/mm2 within two years. This would make CORC magnet cables a very attractive candidate for use in detector and accelerator magnets.
