Abstract:
An rf capacitively-coupled electrodeless light source comprising:a hollow, elongated chamber;at least one center conductor disposed within the hollow, elongated chamber, wherein a portion of each center conductor extends beyond the hollow, elongated chamber;at least one gas capable of forming an electronically excited molecular state, wherein each gas is contained within each center conductor;an electrical coupler positioned concentric to the hollow, elongated chamber, wherein the electrical coupler surrounds the portion of each center conductor that extends beyond the hollow, elongated chamber and wherein the electrical coupler comprises a cylindrical conductor that provides an adjustable capacitance between the center conductor and the hollow, elongated chamber;an rf-power supply positioned in an operable relationship to the electrical coupler; andan impedance matching network positioned in an operable relationship to the rf power supply and the electrical coupler.
