| 摘要 |
THE PRESENT INVENTION RELATES TO A CATHODE STRUCTURE BODY AND A METHOD OF COATING AN EMITTER (107), AND MORE PARTICULARLY, TO INCREASING A CATHODE CURRENT DENSITY AND EXTENDING AN ELECTRON EMISSION LIFETIME BY DEFORMING THE STRUCTURE OF THE EMITTER COATED ON THE TOP SURFACE OF A BASE METAL OF THE UPPER PORTION OF A CYLINDRICAL CATHODE SLEEVE (103). A CATHODE STRUCTURE BODY EQUIPPING A CYLINDRICAL CATHODE SLEEVE (103) IN WHICH A HEATER (104) FOR A CATHODE IS INSERTED AND A BASE METAL THAT AN EMITTER IS COATED ON THE UPPER PORTION OF THE CATHODE SLEEVE (103), WHEREIN THE EMITTER (107) COATED ON THE TOP OF SAID BASE METAL COMPRISES COATING AN ACTIVE METAL AND AN ELECTRON EMISSION MATERIAL (106) WITH LAMINATED STRUCTURE.(FIG. 1)
