dc.description.abstract | 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. | en_US |

dc.identifier.citedreference | The rate of power transfer is proportional to the gradient of E1,E1, rather than E1E1 itself. This may be seen when one substitutes Eq. (3) into Eq. (4) and performs integration by parts. | en_US |

dc.identifier.citedreference | BBU growth on a pencil beam that is placed off-center can be easily calculated by using Eq. (4) instead of Eq. (5). We pretend that the total beam current is carried by theith filament that enters Eq. (4). Although the BBU growth of such an off-center beam depends on θiθi its coupling constant ϵ is still much less than ϵ0,ϵ0, the value for an on-axis beam. | en_US |
