Abstract

PURPOSE: To make possible construction of electrodes with high efficiency by fixing the auxiliary electrodes with the stated array interval on the insulated supporting rod and locating successively the electrode with the stated beam aperture on the auxiliary electrode to fix them.
CONSTITUTION: After supporting auxiliary electrodes 20, 21 and 22 with the stated array interval on insulated supporting rod 27 by the use of jig and tool 23 and spacers 24 to 26 and heating them until they are softend, they are pressed to supporting rod 27 and fixed with fusion welding. Then, electrodes 30, 32 and 34 with the stated beam aperture are located and fixed successively on the auxiliary electrodes. Thus, electrode construction with high efficiency is available.
