Experimental studies with a duopigatron gas discharge ion source are described; measurements of the ion current, mass and energy distributions, and current density profiles as a function of the aperture sizes of the source electrodes are reported. Larger aperture diameters were required to minimize damage to the original ion source (configuration described in Rev. Sci. Instrum. 49, 435 (1978)) observed during its operation on the Sandia Intense Neutron Source Target Test Facility. The ''best'' new configuration produces a 200-mA ion beam that contains 52% D/sup +/ at an arc current of 13 A. In addition to the performance measurements, extensive mass analyses of the ionic impurities produced inside of the ion source were carried out. The large aperture sources produce beams that contain approximately 0.5% contaminants. Typical mass spectra are described and the sources of the impurities discussed.
