PVC - an ILC RF Cryomodule software simulator

We are developing the Penn Virtual Cavity (PVC). It is a software Superconducting RF (SRF) cavity simulator that simulates the effect of each component involved in controlling the precise oscillations of the 1.3 GHz fields in the cavities within a cryomodule. The simulator models the SRF cavity as lumped RLC circuits [1]. The effects of the components involved are simulated in PVC as time dependent changes of the current/voltage at the interface of the RLC circuits, as well as time dependent changes in the RLC values themselves. This simulator can be used as an expert tool to study cavity control issues, as well as a learning tool to get a general idea of the RF characteristics of the SRF cavities.
