Abstract:
A DC plasma torch which includes a long lasting thermionic cathode and has a high thermal efficiency. The DC plasma torch employs a solid cathode made of graphite with highly ordered structure such as Pyrolitic Graphite or Carbon-Carbon composites. Furthermore, carbon containing gases will be used as plasma gas. The cathode will allow for theoretically an unlimited lifetime of the cathode.
