Distributed Inter-Strand Coupling Current Model for Finite Element Simulations of Rutherford Cables
Julien Dular, Alexander Glock, Arjan Verweij +1
In this paper, we present the Distributed Inter-Strand Coupling Current (DISCC) model. It is a finite element (FE) model based on a homogenization approach enabling efficient and a…
Acceleration of Multi-Scale LTS Magnet Simulations with Neural Network Surrogate Models
Louis Denis, Julien Dular, Vincent Nuttens +3
While the prediction of AC losses during transients is critical for designing large-scale low-temperature superconducting (LTS) magnets, brute-force finite-element (FE) simulation…
Reduced Order Hysteretic Flux Model for Transport Current Homogenization in Composite Superconductors
Alexander Glock, Julien Dular, Arjan Verweij +1
In this paper, we present the Reduced Order Hysteretic Flux (ROHF) model to describe the relationship between time-varying transport current and internal magnetic flux for composit…
High Field Magnet Programme -- European Strategy Input
B. Auchmann, E. Todesco, A. Ballarino +6
In this submission, we describe research goals, implementation, and timelines of the High Field Magnet Programme, hosted by CERN. The programme pursues accelerator-magnet R&D with…
Simulation of Rutherford Cable AC Loss and Magnetization with the Coupled Axial and Transverse Currents Method
Julien Dular, Fredrik Magnus, Erik Schnaubelt +2
The coupled axial and transverse currents (CATI) method was recently introduced to model the AC loss and magnetization in twisted composite superconducting strands with low computa…
Influence of Critical Current Distribution on Operation, Quench Detection and Protection of HTS Pancake Coils
Mariusz Wozniak, Erik Schnaubelt, Sina Atalay +5
High-temperature superconductor (HTS) coated conductors (CC) are often wound into pancake coils with electrical insulation in-between the turns. The copper terminals are used for c…
