The CREATOR Project: Towards a Computational Electric Machine Laboratory
Sebastian Schöps, Annette Muetze, Herbert De Gersem +3
The Collaborative Research Centre TRR 361/F90 CREATOR (2022-2030) aims at establishing a new paradigm for the simulation-driven design of electric machines. Increasing demands on e…
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 Scattered-Field Formulation for Coupled Geometric Wakefield and Space Charge Field Simulations in Particle Accelerators
J. Christ, E. Gjonaj, H. De Gersem
We propose a self-consistent simulation model for particle beams in accelerators, which includes the impact of electromagnetic wakefields caused by the geometry of the accelerator…
Experimental Validation of HomHBFEM Simulations of Fast Corrector Magnets for PETRA IV
Jan-Magnus Christmann, Laura Anna Maria D'Angelo, Herbert De Gersem +5
This paper presents experimental validation of the homogenized harmonic balance finite element method (HomHBFEM), which we have developed as a dedicated simulation technique for ma…
DC-Biased Homogenized Harmonic Balance Finite Element Method
Jan-Magnus Christmann, Laura A. M. D'Angelo, Herbert De Gersem +2
The homogenized harmonic balance finite element (FE) method enables efficient nonlinear eddy-current simulations of 3-D devices with lamination stacks by combining the harmonic bal…
