Characteristics of a Cold Cathode Type Penning Source and Low Energy Isotope Separation of High Charge States

Measurements of voltage-, current-and gas flow dependencies of a cold cathode Penning source, using different cathode materials, are reported. The influence of the discharge parameters (arc voltage, arc current, magnetic field and gas flow) on the production of higher charge states was studied. The highest observed charge states were Ar9+ , Kr12+ Xe13+ The cold cathode type Penning source with radial extraction proves to have sufficiently low energy spread to permit isotope separation in the source-magnet field. Results for Ar2+, Kr4+ and Xe7+ as well as emittance measurements are given.
