Abstract
A method and apparatus is provided to prevent energy transfer to a gas which is flown through a gas line disposed between a biased member and grounded member. In one aspect of the invention, a semi-conductive sleeve, such as a silicon carbide sleeve, is provided which is disposed about a gas line and is in contact with the gas inlet manifold and the gas outlet manifold and has a resistance less than that of the gas which is flown through the gas line.
