Abstract: Plasma generation source employing dielectric conduit assemblies having removable interfaces and related assemblies and methods are disclosed. The plasma generation source (PGS) includes an enclosure body having multiple internal surfaces forming an internal chamber having input and output ports to respectively receive a precursor gas for generation of plasma and to discharge the plasma. A dielectric conduit assembly may guide the gas and the plasma away from the internal surface where particulates may be generated. The dielectric conduit assembly includes a first and second cross-conduit segments. The dielectric conduit assembly further includes parallel conduit segments extending from the second cross-conduit segment to distal ends which removably align with first cross-conduit interfaces of the first cross-conduit segment without leaving gaps. In this manner, the dielectric conduit assembly is easily serviced, and reduces and contains particulate generation away from the output port.
