Abstract
A temperature-dependent resistivity shunted junction (RSJ) model with a piecewise linear quasiparticle characteristic has been used in simulations to predict the flux dynamics in a superconducting ring containing a single Josephson junction. The computed results for relative flux penetration do not agree well with experimental data at temperatures approaching Tc. This indicates either that the subgap damping is not directly deducible from junction tunneling characteristics, or that the RSJ model is not sufficiently general in this situation.
