Title: Electron beam irradiation device
Inventor: HOSHI YASUHISA
IPC: G21K5/04
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To open and close an electron beam faster than the opening and closing of a mechanical shutter by providing a power source and a switch between an acceleration tube electrode and a filament, and switching voltage between positive or negative. SOLUTION: Two sets of power sources and switches are provided between a filament F and a first electrode E1, the switch SW1 and the negative power source V1 are connected in series, and the switch SW2 and the positive power source V2 are connected in series. At normal operation, since SW1 is closed, SW2 is opened, and the filament becomes more negative potential than the electrode E1, a thermal electron is attracted to the electrode, and an electron beam comes out into an acceleration tube to be accelerated. Reversely, when SW1 is opened and SW2 is closed, the electron is returned to the filament since filament potential is higher than the electrode E1, and an electron ray beam instantly stops. The beam can be blocked only by the opening and closing of the switch, and since a large shutter plate need not be moved, it is performed in a short time.
