Abstract
An rf driven multicusp source capable of generating 1‐ms H− beam pulses with a repetition rate as high as 150 Hz has been developed. This source can be operated with a filament or other types of starter. There is almost no lifetime limitation and a clean plasma can be maintained for a long period of operation. It is demonstrated that rf power as high as 25 kW could be coupled inductively to the plasma via a glass‐coated copper‐coil antenna. The extracted H− current density achieved is about 200 mA/cm2.Keywords
