The 10 cm (grid diameter) duoPIGatron ion source produces pulsed hydrogen ion beams of 10--15 A beam current in the 20--40 keV energy range for a duration of a few tenths of a second. To fulfill the requirement of the next generation of high-power neutral beam injectors for heating plasmas in CTR devices, this source has been enlarged to a version 15 cm in grid diameter. In addition, by utilizing a magnetic multipole line cusp field confinement method, the plasma created is characterized over the 15 cm grid diameter by a noise level within +- 10% and spatial density variations within +- 5% at a density on the order of 10/sup 12/ cm/sup -3/. This larger source has operated reliably and produced a beam current exceeding 30 A of hydrogen at 27 keV. Initial operation of a 20 cm version of this source employing line cusp confinement has produced an extraction current of 60 A at 33 keV.
