3-D Mechanical Modeling of 20 T HTS Clover Leaf End Coils—Good Practices and Lessons Learned / Murtomäki, Jaakko Samuel (CERN ; Tampere U. of Tech.) ; van Nugteren, Jeroen (CERN) ; Stenvall, Antti (Tampere U. of Tech.) ; Kirby, Glyn (CERN) ; Rossi, Lucio (CERN)
Very high electromagnetic forces are generated in the superconducting coils of high field accelerator magnets. The cables, which are used to wind the coils, can withstand limited pressure levels and strains generated during the powering without degradation. [...]

10 kA Joints for HTS Roebel Cables / Murtomaki, Jaakko Samuel (CERN) ; Kirby, Glyn (CERN) ; van Nugteren, Jeroen (CERN) ; Contat, Pierre-Antoine (CERN) ; Sacristan-de-Frutos, Oscar (CERN) ; Fleiter, Jerome (CERN) ; Pincot, Francois-Olivier (CERN) ; de Rijk, Gijs (CERN) ; Rossi, Lucio (CERN) ; Ruuskanen, Janne (Tampere U. of Tech.) et al.
Future high temperature superconductor (HTS) high field magnets using multitape HTS cables need 10-kA low-resistance connections. The connections are needed between the poles of the magnets and at the terminals in a wide-operating temperature range, from 1.9-85 K. [...]

Idealized Coil Cross-Sections with Minimized Conductor Area for High Field Dipoles / van Nugteren, Jeroen (CERN) ; Wolf, Felix (CERN) ; Murtomäki, Jaakko Samuel (CERN) ; Kirby, Glyn (CERN) ; de Rijk, Gijs (CERN) ; Ten Kate, Herman (CERN) ; Rossi, Lucio (CERN)
In the design of superconducting accelerator magnets, the shape of the coil cross-section is mainly driven by the minimization of the conductor volume, constrained by requirements on the central magnetic field and its homogeneity. Such optimizations commonly assume either a Block or Cosine Theta coil type, which is then filled with (pre-determined) rectangular or key-stoned Rutherford cables. [...]

Investigation of REBCO Roebel Cable Irreversible Critical Current Degradation Under Transverse Pressure / Murtomaki, Jaakko Samuel (CERN) ; Kouhia, Reijo (Tampere U. of Tech.) ; Stenvall, Antti (Tampere U. of Tech.) ; Bottura, Luca (CERN) ; Kirby, Glyn (CERN) ; van Nugteren, Jeroen (CERN) ; de Rijk, Gijs (CERN) ; Rossi, Lucio (CERN)
The Roebel cable utilized in High Field accelerator magnets is subject to high transversal electromagnetic forces. The conductor response to exerted pressure depends from the geometry and materials of the cable. [...]

ICED—Inductively Coupled Energy Dissipater for Future High-Field Accelerator Magnets / Murtomäki, Jaakko Samuel (CERN) ; van Nugteren, Jeroen (CERN) ; Kirby, Glyn (CERN) ; de Rijk, Gijs (CERN) ; Rossi, Lucio (CERN) ; Stenvall, Antti (Tampere U. of Tech.)
Future high-field accelerator magnets, like the ones foreseen in the design study of the FCC project and for the EuCARD2 “Future Magnets” program, operate with magnetic fields in the range of 16-20 T. For such magnets the energy density is higher than in the accelerator magnets at present in operation, posing a challenge for the quench protection. [...]

A fast quench protection system for high-temperature superconducting magnets / van Nugteren, Jeroen (CERN) ; Murtomäki, Jaakko Samuel (CERN) ; Ruuskanen, Janne (Tampere U. of Tech.) ; Kirby, Glyn (CERN) ; Hagen, Per (CERN) ; de Rijk, Gijs (CERN) ; Ten Kate, Herman (CERN) ; Bottura, Luca (CERN) ; Rossi, Lucio (CERN)
For reaching very high magnetic fields in fully superconducting magnets, beyond 16 T for particle accelerators dipoles and beyond 23 T for solenoids, the use of High-Temperature Superconductors (HTS) is unavoidable. Due to the high Minimum Quench Energy in HTS these coils are much more difficult to protect against quenches using conventional methods such as quench heaters or Coupling Loss Induced Quench (CLIQ).
