Abstract :
A new type of vacuum arc plasma source, the vacuum arc with a black body assembly (VABBA), was designed to produce a directed plasma jet. In the VABBA, cathode material is emitted into a closed vessel formed by the cathode and anode, re-evaporated from the anode, which is made from a refractory material, and heated by the arc, and a plasma jet is extracted through an aperture in the anode. Images of different stages of the jet development are presented.
