【摘要】 基于准光学腔回旋管(Gyrotron)的电子注结构及微波电路和潘尼管(Peniotron)的工作机理,本文提出一种新型的短波长毫米波器件——准光学腔回旋潘尼管。文中从电子相对论运动方程出发,导出了计算公式,采用计算机模拟,计算了注波相互作用效率,在80KV,100GHz,三次回旋谐波下工作,得到了效率为43％,而外加磁场仅为13.3KG的结果,显示了这种器件作为在短毫米波长下能以常规磁场工作的高效率、高功率源的实际可能性。更多还原

【Abstract】 On the basis of electron-beam configuration and microwave circuitry of Quasi-Optical Gyrotron together with the operational mechanism of Peniotron, this paper proposes a new kind of device operating at short millimeter wavelengths——Quasi-Optical Gyro-Peniotron at high cyclotron harmonic. Starting from the relativistic equations of motion for the electrons, the calculation formulae are derived. By using computer simulation, a beam-wave interaction efficiency of 43% is obtained for the third cyclotron harmonic at frequency 100 GHz, beam voltage 80 KV and the applied magnetic field 13.3 KG, indicating that this tube will be potentially a high-efficiency high-power source not requiring a superconduction magnet system even at short millimeter wavelengths.更多还原
