Electrical characterization of a d.c. non-transferred plasma torch

Non transferred arc plasma torches are often used as plasma sources for the treatment of toxic and hazardous halogenated substances. At the IFP-CNR in Milan, a research program has been carried out for the development of some types of plasma torches with integrated waste injection systems. In this paper the electrical characterization of the Hollow Cathode Plasma Torch is studied. 1. Introduction The main
