Embodiment Construction
[0028] An embodiment of an ion source device according to the present invention will be described with reference to FIG. 1 . FIG. 1A is a front view of the ion source device viewed from the extraction part side of the ion beam, but assumes a case where the suppression electrode 14-1 and the ground electrode 14-2 shown in FIG. 1B are excluded.
[0029] [structure]
[0030] In FIG. 1 , the ion source device includes an arc chamber 10 having a space for forming plasma. The arc chamber 10 has a cylindrical shape. Here, the cylindrical arc chamber 10 is placed horizontally to form an electron source on one end side (back side) in the direction of the central axis. Like the electron source described in FIG. 3 , the electron source in this ion source device also includes a filament 11 and a cathode 12 . The cathode 12 emits thermal electrons for generating beam electrons that ionize neutral molecules from its thermal electron emitting surface. A reflector 13 is provided inside the...
