Nb-Ti, MgB2 and ReBCO: a combination of conventional and novel superconductors for the powering of the HL-LHC magnets. Demo 2 and Demo 3 demonstration systems were successfully qualified at CERN in 2020.
REBCO conductor tapes reached a world-record critical current at 20T, strengthening the possibilities for a demonstrator of high-level accelerator magnets. Lucio Rossi, leader of the HL-LHC project, explains.
