摘要
提出了一种新的高功率宽带放大器,它由速调管和自由电子脉塞组成,用永久周期磁铁聚焦。研究了这种器件的电子束聚焦、群聚和辐射。在速调管提供一阶调制系数为30%,波导管的半径1.51cm,摇摆器的磁场振幅0.16T,周期7.92cm,电子束的电压490kV,电流50A和半径0.368cm的条件下,预估这种器件的辐射波频率为11.4GHz,输出辐射功率为18MW,输出辐射带宽为44%。
In this paper, a new high power and wideband amplifier with permanent periodic magnet(PPM) focusing is presented. It consists of klystron and FEM . Focusing, bunching and emiting of the electron beam in this device are studied theoretically. The radiation parameters of the device have been estimated as the frequency is 11.4GHz, output power 18MW and output bandwidth rate 44% at the conditions in which a order of modulating coefficiency is 30% of the klystron, radius of the waveguide 1.51cm, the amplitude 0.16T and period 7.92cm of the magnetic field of the wiggler, and the voltage is 490kV, current 50A and radius 0.368cm of the electron beam.
