A pulsed source of H/sup -/ ions has been constructed with minimal cost and is currently being used for commissioning of the Indiana University Cyclotron Facility (IUCF) Cooler Injector Synchrotron. A commercially available duoplasmatron, previously used with the IUCF cyclotrons, was modified for pulsed operation and has produced 25 keV H/sup -/ ion beams of up to 1 mA in an emittance of less than 0.38 /spl pi/-mm-mrad normalized (80%) and can operate up to 10 Hz with 50 /spl mu/s to 4 ms pulse length. A simple and economical pulsed high-power MOSFET circuit is used to drive the arc and the gas valve. The beam transport line to the 7 MeV RFQ-DTL, features an Einzel lens doublet immediately upstream to match the beam from the source. The design, development and performance of the ion source and beam transport line is presented.
