    • Abstract


      Two ion sources of the charged particle oscillator type are described. The discharge chamber consists of an outer cylinder as cathode and an axial wire or a pair of wires along the axis as the anode. The energy spectra and ionic composition of the ion beam have been measured with a double focusing mass spectrometer of the Mattauch-Herzog design constructed in the laboratory. A high percentage of dissociated ions and multiply charged ions has been observed in the ion beam. A brief description of the mass spectrometer is also given.
