Abstract
A H-2/Ar cascaded arc plasma source has been experimentally characteri zed by determination of the efficiency, the electric field, and the pr essure gradient of the arc. The results show that the efficiency of a H-2/Ar cascaded arc drops when the hydrogen flow rate is increased. Th e electron temperature in the argon cascaded arc has been derived to b e in the range 9000-12 500 K. For a hydrogen arc, the mass dissociatio n degree of hydrogen molecules has been derived to be above 60%.
