Apparatus for Efficiently Accelerating Electron Beam through Forming Increase Structure of Plasma Density

摘要

PURPOSE: An apparatus for efficiently accelerating electron beams by increasing plasma density is provided to prevent the limitation of electronic energy causing dephasing by efficiently increasing the electronic energy. CONSTITUTION: A gas discharge unit(501) of a ring shape surrounds a through hole(503) in which a center portion is empty. The gas discharge unit receives gas through a symmetrical gas inlet(504). The received gas is sprayed through the gas discharge unit surrounding the through hole. Lasers travel toward a perpendicular direction of a nozzle for the through hole in an overlap region of the sprayed gas. Plasma density increases to the nozzle. The gas received through the gas inlet is sprayed through the gas discharge unit of the ring shape surrounding the through hole.
