Abstract
A compact, 2.5 cm diam rf-driven multicusp ion source has been develop ed and tested for H+ ion production in pulse mode operation. The sourc e is optimized for atomic hydrogen ion species and extractable current . It is found that hydrogen ion beam current densities in excess of 65 0 mA/cm2 can be achieved with H+ species above 80%. The geometry and p osition of the porcelain-coated copper antenna were found to be of gre at significance in relation to the efficiency of the ion source.
