Abstract
829,783. Ion sources. COMMISSARIAT A. L'ENERGIE ATOMIQUE, and CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. March 20, 1956 [March 26, 1955], No. 8717/56. Class 39(1). In an ion source comprising a probe electrode composed of the element from which the ions are to be produced or an alloy or compound thereof, a plasma of ions is formed in the vicinity of the electrode and the ions are ejected from the electrode by a sputtering process in which the electrode is bombarded by positive ions of the plasma, the electrode being charged negatively with respect to the plasma. The plasma is formed in a suitable gas e.g. a rare-gas, chlorine, nitrogen or the vapour of the element of which the electrode is made, and may be produced by a beam of electrons on a H.F. discharge. In Fig. 1 the electron beam produced by cathode 2 and anode 3 is confined by an axial magnetic field H. The probe electrode 4 within a casing 1 may be replaced by a graphite cylinder provided with a lining of the element to :be disintegrated or may be in the solid or liquid state and may be a conductor or semi-conductor or made of insulating material. Specific elements mentioned are molybdenum, palladium, iron and copper. In Fig. 6 a H.F. discharge is produced by a coil 17 within a cylinder 11 containing a sheet 12 of the element to be disintegrated. The ion source is suitable for ion accelerators or electro-magnetic isotope separators.
