| Abstract: | 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. |
