Electric Gradient Breakdown Results for the Orthogonal Box Cavity in a 3 T Magnetic Field.

摘要

The Muon Collaboration has developed a theory for A method to suppress high electric field breakdown in vacuum cavities in high magnetic fields that are needed for a muon collider or neutrino factory. It has been shown in our studies and by others that high gradient electric field emitted electrons (dark current) are the primary cause of breakdown. A DC magnetic field orthogonal to the RF electric accelerating field prevents dark current high field emitted electrons from traveling across the accelerating gap and therefore will prevent breakdown. We have built a test cavity (TM?2473?APC) in the shape of a box to test this theory. The results of the first study are presented.
