摘要
本文从冷阴极启动角度出发,综合回轰阴极产生的二次电子平均速度与慢波结构上传输的慢电磁波相速同步条件,获得正交场器件的磁场强度与频率的关系。探讨了慢波结构的节距相位移与互作用空间尺寸以及阳极电压间的关系,提出了该类管型互作用空间以及确定工作点的工程设计方法。
Based on cold cathode activation,and the synchronous condition of the average speed of secondary electrons generated by cathode back-bombardment and thephase velocity of slow wave transmitted on the slow-wave circuit,the relationship between magnetic field intensity and frequency in crossed-field amplifiers(CFAs)is obtained.The relationships between the phase displacement of slow-wave circuit and the size of interaction space as well as the anode voltage are discussed,and an engineering method for interaction region design and working point selection of the CFAs is proposed.
