For high current superconductors in magnet fields with currents the order of 50 kA, single ReBCO coated conductors must be assembled a cable. The geometry such cable is mostly that combined torsion, axial and transverse loading states are anticipated tapes tape joints. resulting strain distribution, caused by different thermal contraction electromagnetic forces, will affect critical tapes. Tape performance when subjected to tensile key understanding limitations for composite performance....
We describe the magnet challenges for a Muon Collider, an exciting option considered future of particle physics at energy frontier. Starting from comprehensive work performed by US Accelerator Program, we have reviewed performance specifications dictated beam and operating conditions to satisfy accelerator needs. Among many magnets that make up muon collider, identified four systems represent well envelope challenges: target capture solenoid, final cooling dipoles collider dipoles. These...
