It is shown that an annular electron beam may carry six times as much current as a pencil beam for the same beam breakup (BBU) growth. This finding suggests that the RF magnetic field of the breakup mode is far more important than the RF electric field in the excitation of BBU. A proof-of-principle experiment is suggested, and the implications explored.<>
