【Abstract】 e:A focussed intense electron beam of keV used for atommolecule collision was destribed. The relationships of the electron current with the position of LaB 6 surface, the grid volage, the electron energy and the lens construction were studied.The methode used for extending the electron currend at a lower energy was abtained by a assistant anode extraction.更多还原
