摘要
采用法国的MAFIA程序计算电场 .编制了TRAJ程序 ,用逐点跟踪计算电子轨迹 ,得到了束流包络 .观察了在高压电场中栅压对束流光学传输的影响 ,并获得了在不同能量范围内的栅压聚焦作用 ,为栅压调节提供了理论依据 。
In order to calculate the electron trajectory of 200kV self shielded electron accelerator, the electric field is calculated with a TRAJ program. In this program, following electron track mash points one by one, the electron beam trajectories are calculated. Knowing the effect of grid voltage on electron optics and gaining grid voltage focusing effect in the various energy grades, we have gained scientific basis for adjusting grid voltage, and also accumulated a wealth of experience for designing self shielded electron accelerator or electroncurtain in future.
