    摘要: An electron emission apparatus, an electron gun, and a method of fabrication of the electron gun are provided. The electron gun includes a cathode, a Wehnelt, and an anode. The cathode is configured to provide an electron beam. The Wehnelt has a bore. The bore is configured to pass the electron beam. The anode is disposed proximate to the cathode. The diameter of the bore of the Wehnelt and the offset between the Wehnelt and the cathode satisfy a predetermined dimensional relationship. The predetermined dimensional relationship is at least a function of a diameter of the bore of the anode and a distance between the Wehnelt and the anode.

    摘要: In a flash lamp 1, a front end part 62 of a cathode 60 and a front end part 72 of an anode 70 are opposed to each other on a reference line RL, and with respect to a reference surface RS including the reference line RL, a front end part 82 of a trigger electrode 80 is located on one side, and a front end part 92 of a trigger electrode 90 is located on the other side. Further, a terminal end 82a of the front end part 82 of the trigger electrode 80 and a terminal end 92a of the front end part 92 of the trigger electrode 90 are separated from the reference line RL, and each front end part 82, 92 is formed so as to taper toward the reference line RL. Accordingly, an arc discharge occurs in a limited route R from a terminal end portion of the front end part 62 of the cathode 60 through a terminal end portion of the front end part 82 of the trigger electrode 80 and a terminal end portion of the front end part 92 of the trigger electrode 90 to a terminal end portion of the front end part 72 of the anode 70.

    摘要: An ion source may include first, second, and third electrodes. The first electrode may be a repeller having a V-shaped groove. The second electrode may be an electron emitter filament disposed adjacent the base of the V-shaped groove. The third electrode may be an anode that defines an enclosed volume with an aperture formed therein adjacent the electron emitter filament. A potential of the first electrode may be less than a potential of the second electrode, and the potential of the second electrode may be less than a potential of the third electrode. A fourth electrode that is disposed between the electron emitter filament and the anode may be used to produce a more collimated electron beam.
