On the Stability of Mixed Finite-Element Formulations for High-Temperature Superconductors
Julien Dular, Mane Harutyunyan, Lorenzo Bortot +3
In this work, we present and analyze the numerical stability of two coupled finite element formulations. The first one is the h-a-formulation and is well suited for modeling system…
Proof of Concept of High-Temperature Superconducting Screens for Magnetic Field-Error Cancellation in Accelerator Magnets
L. Bortot, M. Mentink, C. Petrone +11
Accelerators magnets must have minimal magnetic field imperfections for reducing particle-beam instabilities. In the case of coils made of high-temperature superconducting (HTS) ta…
Fast Failures in the LHC and the future High Luminosity LHC*
B. Lindstrom, P. Bélanger, L. Bortot +11
An energy of is stored in each of the two LHC proton beams for nominal beam parameters. This will be further increased to about in the future High…
Numerical Analysis of the Screening Current-Induced Magnetic Field in the HTS Insert Dipole Magnet Feather-M2.1-2
Lorenzo Bortot, Matthias Mentink, Carlo Petrone +5
Screening currents are field-induced dynamic phenomena which occur in superconducting materials, leading to persistent magnetization. Such currents are of importance in ReBCO tapes…
A Coupled A-H Formulation for Magneto-Thermal Transients in High-Temperature Superconducting Magnets
Lorenzo Bortot, Bernhard Auchmann, Idoia Cortes Garcia +6
The application of high-temperature superconductors to accelerator magnets for future particle colliders is under study. Numerical methods are crucial for an accurate evaluation of…
STEAM: A Hierarchical Co-Simulation Framework for Superconducting Accelerator Magnet Circuits
Lorenzo Bortot, Bernhard Auchmann, Idoia Cortes Garcia +7
Simulating the transient effects occurring in superconducting accelerator magnet circuits requires including the mutual electro-thermo-dynamic interaction among the circuit element…
