Theoretical modelling of RF behavior

Trapped vortices can contribute significantly to a residual surface resistance $R_i(H)$ of SRF cavities, but the behavior of an elastic vortex line driven by strong RF Meissner currents through a random pinning potential remains poorly understood. Here we report extensive numerical simulations of large-amplitude oscillations of a trapped vortex under a strong RF magnetic field parallel to a...
