摘要 从同轴腔回旋自谐振脉塞(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腔 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及输出功率对同轴腔的外半径和 电子导引中心半径以及加速电压的变化非常敏感,而对腔体内半径的变化并不敏感。由数值模拟可知,器件 的线性增益能达到294.96 dB/m。 The linear gain is researched by the gyrokinetics of coaxial-cavity CARM amplifier. The influences of the outer-contructor radius, the inner-rod radius, the electron beam radius and beam voltage on the output power and linear gain are investigated. It is shown by optimizing the parameters that the linear gain of the simulation might be raised up to 294.96 dB/m.
