  • Miniature microwave plasma torch application and method of use thereof
    Publication number: 20050223992
    Abstract: A miniature microwave plasma torch apparatus (10) is described. The microwave plasma torch apparatus (10) is used for a variety of applications where rapid heating of a small amount of material is needed. The miniature microwave plasma torch apparatus (10) operates near or at atmospheric pressure for use in materials processing. The apparatus (10) provides a wide range of flow rates so that discharge properties vary from diffusional flow of radicals for gentle surface processing to high velocity, approaching supersonic, torch discharges for cutting and welding applications. The miniature microwave plasma torch apparatus (10) also has a very small materials processing spot size.
