| Description/Abstract | A source of a tubular beam of ions comprising a cylindrical shell with one butt end having an axial hole in it and the other butt end solid is described.^It is provided with a rod having one end fixed to the solid butt end of the cylindrical shell and arranged coaxially to the latter.^The free end of the rod carries a disc placed in the axial hole of the butt end of the cylindrical shell so as to obtain a circular gap confined by the side wall of the hole.^A hollow annular shell is arranged coaxially within the cylindrical shell so that a circular gap made in the butt end of the annular shell faces the circular gap in the butt end of the cylindrical shell.^An annular cathode and an anode are arranged coaxially inside the annular shell.^A thermoelectronic cathode is placed outside the cylindrical shell near to its butt end with the circular gap.^An electromagnet coil is arranged coaxially inside the cylindrical shell.^A device for ion acceleration is placed on the path of emission of the ions.^The cylindrical shell and its butt ends and the rod are made of magnetically soft material, whereas the annular shell is made of non-magnetic material.^5 figures. |
