Zusammenfassung:	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. Cette invention concerne un chalumeau à plasma micro-onde miniature (10) utilisé pour une multitude d'applications qui requièrent un chauffage rapide d'une petite quantité de matière. Ce chalumeau à plasma micro-onde miniature (10) fonctionne à pression atmosphérique ou quasi-atmosphérique dans une application de traitement de matières. Cet appareil (10) offre une vaste gamme de débits, ce qui permet aux propriétés de décharge de varier entre un flux diffus de radicaux en vue d'un traitement de surface doux et des décharges de chalumeau à haute vélocité quasi-supersoniques pour des applications de découpe et de soudage. Le chalumeau à plasma micro-onde miniature (10) présente par ailleurs un point de traitement de matières de très petite taille.
