| Abstract: | The General solutions of space-charge flow and electrode shape are given in the crossed electric and magnetic fields electrode system in which the cathode operates under arbitrary condition.The effects of the cathode surface electric-field and electron initial velocity on the elec- trode shape and characteristics of electron beam are calculated and analysed.The results of calcu- lation and analysis show that the effets of the electrode shape and electron initial velocity on the characteristics of electron beams can be decreased by means of increasing cathode surface electric field intensity,when the cathode operates under temperature limited. |
