Abstract
An induction plasma torch comprises a tubular torch body, a plasma confinement tube disposed in the tubular torch body coaxial therewith, a gas distributor head disposed at one end of the plasma confinement tube and structured to supply at least one gaseous substance into the plasma confinement tube; an inductive coupling member embedded within the tubular torch body for applying energy to the gaseous substance to produce and sustain plasma in the plasma confinement tube, and an electrically conductive capacitive shield on an inner surface of the tubular torch body. The capacitive shield is segmented into axial strips interconnected at one end. Axial grooves are machined in the inner surface of the tubular torch body, the axial grooves being interposed between the axial strips.
