Description
Field emission is one of the major problems limiting rf cavity performance in accelerators. Superconducting cavities are made of thin metal shells in a metal liquid helium vessel. This system can be viewed as a Cerenkov radiator between a set of mirrors. Field emitted electrons can punch through the cavity wall and generate Cerenkov light in helium which can be collected by appropriate photodetectors. We report on GEANT4 simulation of electron and Cerenkov photon transport in a TESLA-type superconducting cavity to evaluate the feasibility of this method.
