本文首次从电子回旋谐振脉塞(ECRM)非线性軌道理论的一般原理出发,分析了人们颇感兴趣的回旋管内电子注能量和动量离散问题。文中简要讨论了三种产生回旋电子注的方法及引起能量和动量离散的原因。在此基础上提出了考虑能量和动量离散的轨道理论物理模型。文中以圆柱波导单腔回旋管和准光腔回旋管为例,对动量和能量离散的影响进行了非线性分析。结果表明,较大范围的离散对普通波导型腔体回旋管效率的影响并不大,而对准光腔回旋管则与电子注的注入方式有重要关系。 本文采用动量能量关系式作计算监测。它比用正角动量P_φ几作监测量有更大的普适性,计算也更简便。
In this paper, for the first time, based on the general principle of non-linear orbital theory of electron cyclotron resonance pulse plume (ECRM), we analyze the problem of energy dispersion and momentum dispersion in the gyrotron. In this paper, three methods for generating cyclotron electron injection and the reasons for the discretization of energy and momentum are briefly discussed. On this basis, a physical model of orbital theory considering the discretization of energy and momentum is proposed. Taking the cylindrical waveguide single-cavity gyroscope and quasi-optical cavity gyrocompass as an example, nonlinear effects of momentum and energy dispersion are analyzed. The results show that the dispersion in a wide range has little effect on the efficiency of the convoluted tube in a conventional waveguide cavity, and the alignment of the cavity resonator has an important relationship with the injection method of the electron beam. In this paper, we use the momentum energy equation for the calculation and monitoring. It is more general than the amount of positive momentum P_φ for monitoring, the calculation is also more convenient.
