Design of a 320 kV Ion Accelerator for Multiply Charged Heavy Ions

An accelerator for multiply charged ions with a terminal voltage of 320 kV has been developed. A pulsed cold cathode P.I.G. ion source with titanium cathodes and side extraction is immersed in a magnetic field, to analyze and focus the beam into the entrance aperture of the post accelerating column. Matrix calculations of the ion optics are given. After the accelerator the beam can be focussed with an electrostatic triplet into a gascell. The charge exchanged beam is analyzed in a magnet provided with several exit gates for the respective charge states.
