Abstract :
High current dc ion sources suitable for use in accelerators are being developed. Two such sources are described - a duoplasmatron source to provide 25 mA dc of deuterons for the Fast Intense Neutron Source (FINS) accelerator; and a duoPIGatron source with a multiaperture extraction column to produce a 50 keV, 500 mA dc proton beam (~ 750 mA dc total current). The final design for the FINS source is presented and the factors most strongly affecting source performance are identified. Initial experiments with the high current source (to 450 mA total current) are described. Accurate measurements of beam emittance at various currents are presented.
