The development, characteristics and emittance of the Penning discharge ion source used in the Cosmotron injector are described. The maximum value of brightness reported is 3 × 1012 mA cm-2 rad-2 at 78 mA total current, 23 keV beam energy. The results are superior to recent values for duoplasmatrons from various laboratories, except for total current.
