摘要

稳定运行是行波管设计的难点之一。耦合器处的不匹配，由于空间电荷力等原因，光束的扩展超过了必要的范围，可能导致管的自激。光束的扩散也可能导致反向波振荡[1]。因此，束的聚焦是行波管工作中的一个重要问题，束的聚焦需要强磁场的约束。在本研究中，将研究给定光束参数下磁场的下限。CST Studio Suite将用于Ku波段行波管的建模和模拟[2]。

Investigating a Lower Limit for the Magnetic Field in a TWT*

Stable operation is one of the challenging difficulties of a traveling wave tube when it comes to designing. Mismatches at the couplers, spreading of the beam more than necessary due to space-charge forces etc. may lead to self-excitations of the tube. The spreading of the beam may also lead to backward wave oscillations[1].For this reason the beam focusing is an important matter on TWT operation and strong magnetic fields are required for the confinement of the beam.In this study a lower limit for the magnetic field will be investigated for given beam parameters. CST Studio Suite will be used for modelling and simulations of a Ku band TWT [2].
