摘要

我们提出了一种基于模式与比例方位角指数和接近特征值耦合的大电流回旋管狭缝腔的变型。通过有限元仿真，验证了该方法的高选择性。在0.3 THz和0.5 THz波段对输出功率约为70 - 80mw的大电流相对论回旋管进行了三维PIC模拟。

High-current THz-band gyrotrons based on axial-slit cavities

We propose a variant of a slotted cavity for high-current gyrotrons based on the coupling of modes with proportional azimuthal indexes and close eigenvalues. A finite-element method simulation is presented, which confirm its high selectivity. 3D PIC simulations of a high-current relativistic gyrotron in the 0.3 THz and 0.5 THz bands with an output power of about 70–80 MW are performed.
