AASC is presently developing a vacuum arc ion source for Heavy Ion Fusion (HIF) and other commercial applications. Induction linear accelerators that produce energetic heavy ions beams are a prime candidate for power-producing fusion reactors. A source of heavy ions with low emittance and low beam noise, 1+ to 3+ charge states, {approx}0.5 A current, 5--20 {micro}s pulse widths and {approximately}10 Hz repetition rates is required. A gadolinium (A {approx} 158) ion beam with {approx}0.12 A beam current, 120 keV beam energy, {approx}2.5 cm diameter extraction aperture and 20 {micro}s pulse width has been produced for HIF studies. The authors have measured that >80% Gd ions were in the 2+ charge state, the beam current fluctuation level (rms) was {approx}1.5% and the beam emittance was {approx}0.3 {pi} mm mrad (normalized). With {approx}8 {times} 10{sup {minus}5} torr background gas pressure, the beam was well space-charge neutralized and good propagation of the 20 {micro}s long Gd ion beams was observed. Details of the work will be presented. The results of the experiment imply that the vacuum arc ion source is a highly promising candidate for HIF applications.
