摘要
从同轴回旋自谐振脉塞(CARM)放大器的回旋动力学理论入手,详细分析了各参量对同轴CARM放大器的线性增益的影响。通过数值模拟,发现该器件的线性增益对及对同轴波导的外半径、电子导引中心半径以及加速电压的变化非常敏感,而随波导内半径的变化不敏感。经优化,当外半径为3.805 cm,导引中心半径为1.309 cm,内半径为1.039 cm,加速电压为54.9 kV时,器件的线性增益最高为294.96 dB/m。
In the paper the linear gain of coaxial-cavity cyclotron autoresonance maser amplifier is researched by the gyrokinetics. The outer-contructor radius, the electron beam radius and beam voltage＇s change on the linear gain is great, but the influence of the inner-rod radius＇s change on the linear gain is small. It is shown by optimizing the parameters that the linear gain of the simulation might be raised up to 294.96 dB/m that the outer-contructor radius is 3. 805 cm, the inner-rod radius is 1. 039 cm, the electron beam radius is 1. 309 cm, beam voltage is 54.9 kV.
