ABSTRACT:
A downstream plasma reactor system is presented. The reactor system includes a reaction chamber. An inlet conduit is connected to the reaction chamber. A plasma tube is coupled to the inlet conduit. A sealing member is interposed between the plasma tube and the inlet conduit. A blocking member, preferably containing a fluorocarbon polymer, is also interposed between the plasma tube and the inlet conduit. The blocking member is positioned closer to the discharge opening of the plasma tube than the sealing member and is preferably capable of preventing a substantial quantity of plasma-generated reactive species from reaching the sealing member during operation of the reactor system.
