A Method for Operating an Iris Loaded RF Separator Structure at Low Momentum

Because iris loaded separator structures can be operated at phase velocities other than c, it is possible to develop "low" momentum RF separated beams using iris loaded deflectors. This report describes a "low" momentum RF beam separator using two iris loaded deflectors. This is accomplished by adjusting the RF phase velocity to be in synchronism with the wanted particles. The wanted particles thus receive large deflections. The unwanted particles, because they undergo large phase slips in passing through the deflector, receive small deflections.
