Abstract:
There is provided a coaxial-cable coupled and water-cooled SWP (surface wave plasma) generator, wherein the generator comprises: a hollow connector (100) having a first inner space defined therein; a coaxial-cable (200) connected to the hollow connector (100), wherein the cable (200) has a core (210) configured to transmit an electromagnetic wave from an electromagnetic wave oscillating unit to the hollow connector (100), wherein the core (210) extends into the inner space of the hollow connector (100); a dielectric tube (300) having a first end portion electromagnetically coupled to the hollow connector (100) so that the electromagnetic wave transmitted into the hollow connector (100) is electromagnetically inputted into the dielectric tube (300); and a discharge gas injection unit (400) fluid-communicating with the dielectric tube (300) to inject a discharge gas into the dielectric tube (300).
