Nonlinear simulation of a coaxial gyro-amplifier with external electrostatic voltage

摘要: 对一种工作频率为0.14THz的小轨道同轴回旋管放大器进行非线性模拟,结果表明：通过加载外部静电压的方法,可将回旋管放大器的饱和输出功率提高19%,而且电子束横向与纵向速率比以及横向速度离散对输出功率都没有明显影响,从而可以有效提高回旋管放大器性能.

Abstract: A proposal is presented to enhance the saturation output power of a small-orbit coaxial gyro-amplifier by employing an external electrostatic voltage. Nonlinear simulations show that improved saturation output power increases 19 % for a transverse electric mode at a frequency of 0.14 THz. Both the ratio of the electron-beam transverse velocity to the axial velocity and the spread of transverse velocity do not cause obvious influence on the saturation power. Therefore the performance of gyro-amplifier is effectively improved.
