摘要

本文对c波段宽带MBK射频输出包络的肩部和倾斜进行了描述和讨论。射频包络肩主要发生在工作频带的低频段，是由覆盖在腔壁上的微波衰减材料fesal气体产生的。射频包络倾斜是由脉冲电压的下降和效率与波束电压的依赖关系引起的。本文对这些物理现象进行了解释和分析。讨论了克服射频包络肩和减小射频包络倾斜的方法。

The research on RF output envelope of C-band Multi-Beam Klystron

The shoulder and the tilt of RF output envelope of the C-band broadband MBK are described and discussed in the paper. The RF envelope shoulder occurs mainly at low part of the operating frequency band, and is caused by the gassing of microwave attenuation material FeSiAl covering on the wall of the cavity. The RF envelope tilt is caused by the drop of the pulse voltage and the dependence of efficiency on the beam voltage. These physical phenomena are explained and analyzed in the paper. The methods for overcoming the RF envelope shoulder and reduce the RF envelope tilt are also discussed.
