Abstract

Remodeling components from two commercially available spark plugs and adding tungsten wire as the central electrode construct a cylindrical-shape magnetized plasma torch module. A ring-shaped permanent magnet is used to provide an axial magnetic field, which rotates the discharge to prevent the formation of hot spots. The electric properties of this magnetized torch module are studied and compared with those of the unmagnetized one. This module is designed as a unit of a torch array for plasma generation. A new diagnostic method based on microwave absorption is introduced, by which the spatially averaged time functions of the density and temperature of torch plasma are measured. An array of four torches is demonstrated.
