摘要
结合箔聚焦和静电线聚焦的特点,对箔聚焦强流相对论环形电子束在同轴波导中的传输进行了研究。通过数值求解电势满足的泊松方程,得到电势、电场分布及系统的空间电荷限制流,并根据电子的运动方程得到包络电子的平衡条件及其运动轨迹。
Combining the characteristics of foil focusing and electrostatically-charged wire focusing, the transmission of foil- focused intense relativistic annular electron beam in a coaxial cylindrical waveguide is studied. The electric filed and the spacecharge-limited current is derived by calculating Poisson equation via numerical calculation. The equilibrium conditions and tracks of envelope electrons are attained through motion the electron equation.
