Cumulative interaction in the deflection cavities of a high-power magniconamplifier

A major factor limiting the output power of a high-power magnicon is RF bre akdown in its penultimate cavity, Utilization of the principal of angle sum ming [2] allows us to achieve cumulative interaction between a beam and RF fields of the magnicon deflection system, and thus to decrease the maximum electric field in the penultimate cavity, In this paper, the problems of im plementing a cumulative interaction in a magnicon deflecting system are dis cussed, A deflecting system with coupled cavities working according to the principal of angle summing, which has been tested with success experimental ly, has a limitation Caused by instabilities that can limit pulse duration at a bower level higher than a few tens of milliwatts. The method described employs a set of uncoupled penultimate cavities to obtain cumulative inter action at high power without sacrifice of pulsewidth.
