We analyze the motion of the electron beam in the collector of a gyrotron with the shielded magnetic system. The methods of optimization of the collector are proposed, depending on the limitations imposed on its transverse dimensions. Calculations are performed for collectors of the technological gyrotrons capable of operating in a wide range of magnetic fields (1.0–1.8 T), which allows generating radiation at a frequency of 24 to 48 GHz at the fundamental cyclotron resonance and, correspondingly, up to 100 GHz when exciting oscillations at the second gyrofrequency harmonic.

屏蔽磁系统优化技术回旋管集电极系统

我们用屏蔽磁系统分析了回旋加速器集电极中电子束的运动。根据对收集器的横向尺寸的限制，提出了对收集器进行优化的方法。对能够在宽范围的磁场（1.0–1.8 T）中运行的技术回旋管的收集器进行了计算，该回旋管允许在基本回旋共振处产生频率为24至48 GHz的辐射，相应地，该辐射可高达100二次陀螺频率谐波激发振荡时的GHz。
