本文给出了具有正交直流场的边廊模回旋脉塞的线性和非线性分析。对模型的小信号起振,同轴腔内导体对模式的截止频率和分割度的影响以及外加电压对电子回旋频率,起振束功率和互作用效率的影响作了较详细的研究。计算表明,对m=2,互作用效率可达41%。我们还将其结果与相同条件下圆柱腔情况作了比较。这些分析有益于工程设计。 In this paper, the linear and non-linear analysis of the gyrocompass plugging of a side-porch model with an orthogonal DC field is given. The effects of small signal excitation of the model, the cutoff frequency and cutoff of the coaxial conductor in the coaxial cavity and the influence of the applied voltage on the electron cyclotron frequency, the oscillating beam power and the interaction efficiency are studied in detail. Calculations show that for m = 2, the interaction efficiency can reach 41%. We also compare the results with the cylindrical cavity under the same conditions. These analyzes are good for engineering.
