More specifically, the present invention relates to a species. A large-area negative ion beam source is shown. The geometry of the large-area area may be circular. Can be rectangular. BACKGROUND OF THE INVENTION Please refer to U.S. Patent No. M66,941 and Ishikawa's NegatiVeqon s〇urces fοr M odifi Jia Rushan published in Rev. 〇f Scientific Instruments, 67, (30), March, 1966. Ishikawa manufactures secondary negative ions by using argon or krypton discharge and planing steam. There are two differences between the present invention and those disclosed by Ishikawa: (1) The present invention uses traditional magnetron sputtering The source is shot, and the traditional magnetron sputtering source is improved by adding a planer V. (2) Ishikawa introduces the planer from the front surface of the target, and the present invention introduces the planer from the rear side (that is, via the target However, the present invention is not limited to the direction of such planing supply. One of the novel main features of the present invention is the use of a magnetron sputtering source, and the insulating vapor can be from the side or front of the target. Introduction. Detailed description of the invention The sub-source contains two main parts .... (丨) The magnetron sputtering source that provides and sustains the discharge. Because the target is negatively biased in relation to ground and plasma potential, argon ions in the discharge will hit the target. 2) The reservoir provides cesium vapor supply to the magnetron sputtering source, so that the negative ion plutonium is sputtered from there. Plane is recharged from the storage planer, and then injected 499495 through the back of the target. 5.
