Notes:
A high current, light ion duoplasmatron ion source was designed and has been brought into operation. This ion source has been designed to deliver up to a maximum of 20-mA light ion beam at an energy of 20 keV and will serve as an injector to the RFQ accelerator. The magnetic field mapping in the anode column region and studies of the filament characteristics have been carried out. The effects of the gas pressure, magnetic field, puller voltage, and screen voltage on the ion current have been studied to obtain the optimized values. The spatial beam distribution has been mapped in two orthogonal planes. So far the source has yielded about 12 mA of unanalyzed proton beam at an extraction voltage of 15 kV and arc current of 2.5 A. Tests at higher extraction voltages and the detailed beam emittance studies are being carried out.
