Abstract

A plasma generation system is provided that includes an elongated plasma chamber having a first elongated side wall substantially parallel to a longitudinal axis extending through the plasma chamber and a gas delivery device for delivering a gas to the plasma chamber via the first elongated side wall. The gas delivery device includes at least one input port for receiving a source of the gas and a plurality of output ports for delivering portions of the gas to the plasma chamber. The gas delivery device also includes a network of gas delivery paths comprising at least one branch point between the at least one input port and the plurality of output ports. The at least one branch point is directly connected to (i) an input node and (ii) at least two output nodes that are positioned offset from the branch point along the longitudinal axis.
