摘　　要：带状电子注器件(或平面结构器件)是一种新型的高功率毫米波、亚毫米波源。其中,如何产生带状电子注对于该种器件来说至关重要。本文基于对射线方程的研究,猜想椭圆螺线管能够实现常规圆柱电子注到带状电子注的转换。采用3D粒子模拟,验证了我们的猜想。并调节电子注参数和螺线管参数得到了所需的带状电子注。本文的研究为下一步带状电子注器件的研究打下了坚实的基础。A novel technique has been successfully developed to generate the highly elliptical sheet electron beam to meet the stringent demands in the development of an emerging class of high power, high-frequency microwave sources. The idea behind the shape transformation technique is that based on Paraxial Ray Equation, the sides of cylindrical solenoid were ＂compressed＂ in such a way that its ellipsoidal cross-section approaches to that of a sheet. The circular-to- elliptical shape transformation of electron beam was simulated with 3-dimension particle-in-cell model to verify the design principle. Besides, the impacts of various factors, including structures of both the electron beam and the magnetic field were carefully evaluated to generate the optimized highly elliptical sheet electron beam.
