| 摘 要： | 带状电子注真空器件是一种很有潜力的高功率微波毫米波器件,其中带状电子注的稳定传输和聚焦是该器件的关键。针对带状电子注的聚焦和传输,提出采用周期椭圆螺线管结构来稳定传输高椭圆率的带状电子注。通过理论分析,得到椭圆螺线管的磁场分布情况,研究了该磁场下带状电子注的运动情况,并且推导出带状电子注在周期椭圆螺线管结构中稳定传输的条件。最后,采用粒子模拟验证了该稳定传输条件。

| Abstract: | Stable sheet electron beam transport or focusing is critical for the sheet electron beam vacuum electronic device (VED) which is a kind of promising high power device in millimeter and sub-millimeter wave band. This paper proposes a periodic elliptical solenoid structure for the transport of high-elliptical sheet electron beams. The magnetic field of the elliptical solenoid is analyzed, and the conditions for the stable transport of sheet beams in the structure are derived. Particle-in-cell simulations are conducted and verify the conditions. |

| Keywords: | periodic elliptical solenoid high power millimeter wave sheet electron beam focusing Mathieu function |
