31. Thermal Analysis of He II-cooled Nb3Sn Superconducting Coil Samples for the HL-LHC Particle Accelerator Project

20/09/2021, 12:25

The High Luminosity upgrade of the Large Hadron Collider (HiLumi-LHC) foresees the installation
of Nb3Sn based dipoles (11T Dipole) and quadrupoles (MQXF) at select points of the
accelerator. The precise knowledge of its thermal characteristics and heat extraction performance in response to deposited loads is essential
in determining safe operating margins of the magnets. These...

36. Sensitivity analysis on material properties in mechanical analysis of YBCO tapes during axial and transverse loading

20/09/2021, 12:50

High Temperature Superconductor (HTS) tapes are expected to enable future magnets to reach magnetic fields beyond 20 T. Detailed knowledge on how these composite coated conductors behave is needed to design reliable magnet applications. The mechanical strain causes the YBCO layer within the tape to degrade, meaning that its critical current I_c drops, leading to under-performing devices. The...

37. Electro-mechanical modeling of the fusion cables

20/09/2021, 13:15

Until today several designs of the Nb3Sn Cable-In-Conduit Conductors (CICCs) have been developed for different high-performance tokamak magnets. The Nb3Sn strands composing the conductors are submitted to mechanical stresses of electromagnetic (EM) and thermal origin, inducing local deformations and affecting the strands critical current carrying capability. Even though it is possible to test...
