    Abstract: An apparatus for abatement of gases is provided. The apparatus includes a toroidal plasma chamber having a plurality of inlets and an outlet, and at least one chamber wall. One or more magnetic cores are disposed relative to the toroidal plasma chamber. The plasma chamber confines a toroidal plasma. A second gas inlet is positioned on the toroidal plasma chamber between a first gas inlet and the gas outlet at a distance d from the gas outlet, such that a toroidal plasma channel volume between the first gas inlet and the second gas inlet in the is substantially filled by the inert gas, the distance d based on a desired residence time of the gas to be abated.

    Abstract: Methods and systems are provided for heating a dielectric preform material. An exemplary method includes inserting the preform material into a microwave cavity along a longitudinal axis of the microwave cavity and supplying the microwave cavity with microwave power having a frequency that corresponds to an axial wavelength along the longitudinal axis of the microwave cavity. The axial wavelength is greater than a length of the preform material along the longitudinal axis. The method includes heating the preform material within the microwave cavity by the microwave power and determining temperatures of the preform material at one or more locations on a surface of the preform material. The method further includes adjusting, based on the temperatures of the preform material, the microwave frequency to achieve substantially uniform heating at least on a sidewall of the preform material along the longitudinal axis.

    Abstract: An apparatus for generating plasma includes a plasma discharge tube and a conductive coil helically wound around an outer surface of the plasma discharge tube. A waveguide is coupled to a microwave cavity surrounding the plasma discharge tube to guide the microwave energy into the plasma discharge tube such that the plasma is generated in the plasma discharge tube. The waveguide is positioned such that an electric field of the microwave energy is oriented at a predetermined angle with respect to the longitudinal axis of the plasma discharge tube. A resulting induced electric current in the conductive coil affects power absorption in the plasma discharge tube, the predetermined angle being selectable such that power absorption in the plasma discharge tube is according to a predetermined profile with respect to the longitudinal axis of the plasma discharge tube.
