Abstract

L'invention concerne un dispositif et un procédé de génération d'un gaz ionisé ou plasma par ondes hyperfréquences. Le dispositif comprend une enveloppe 18 contenant un gaz ionisable et au moins un circuit oscillant autonome et isolé composé d'un auto-inducteur et d'un condensateur situé dans l'enveloppe au coeur du gaz ionisable et adapté pour conférer au circuit un coefficient de surtension à vide supérieur à 1. Sous l'effet d'un rayonnement électromagnétique de fréquence voisine à la fréquence Fo du circuit oscillant, le circuit produit dans le condensateur une tension d'amorçage assurant ionisation du gaz.
