Numerical quality factor statistics for SRF cavities with spatially inhomogeneous multilayer coatings modeled by Gaussian random fields
Aaron Gobeyn, Wolfgang Ackermann, Herbert De Gersem
Bulk niobium has long been the material of choice for superconducting radio-frequency applications. An alternative approach is the superconductor-insulator-superconductor multilaye…
Multilayer model for coatings with arbitrary layers for superconducting radio-frequency applications
Aaron Gobeyn, Wolfgang Ackermann, Herbert De Gersem
We extend the multilayer model of \etal{Kubo} for superconductor-insulator-superconductor (SIS) structures in two ways: first, by generalizing it to arbitrary sequences of layers o…
A Dynamic Energy-Based Hysteresis Model for Pulsed-Operated Fast-Ramping Magnets
Dominik Moll, Laura A. M. D'Angelo, Herbert De Gersem +3
Due to the strongly nonlinear behavior of ferromagnetic yokes, the numerical analysis of fast-ramping magnets is highly cumbersome and, therefore, in practice overly simplified by…
Evaluation of Torque Ripple and Tooth Forces of a Skewed PMSM by 2D and 3D FE Simulations
Karsten Müller, Andreas Wanke, Yves Burkhardt +1
In this paper, various skewing configurations for a permanent magnet synchronous machine are evaluated by comparing torque ripple amplitudes and tooth forces. Since high-frequency…
Homogenized harmonic balance finite element method for nonlinear eddy current simulations of fast corrector magnets
Jan-Magnus Christmann, Laura Anna Maria D'Angelo, Herbert De Gersem +5
This paper develops a homogenized harmonic balance finite element method (HomHBFEM) to predict the dynamic behavior of magnets with fast excitation cycles, including eddy current a…
A Parallel-In-Time Adjoint Sensitivity Analysis for a B6 Bridge-Motor Supply Circuit
Julian Sarpe, Andreas Klaedtke, Herbert De Gersem
This paper presents a parallel-in-time adjoint sensitivity analysis which combines a transient adjoint sensitivity analysis with the parareal approach in order to significantly spe…
