Abstract

Une source de lumière comporte une pièce cylindrique circulaire (2) de quartz formant une enveloppe ou un creuset de plasma solide. Le quartz est transparent à la lumière visible et les surfaces externes du quartz sont polies. Le creuset a une longueur l et un diamètre d. Un vide (3) est aligné de façon centrale. Il est court et de petit diamètre par rapport aux dimensions du creuset lui-même. Le vide est rendu étanche. Un remplissage insaturé de matériau excitable par micro-ondes (9) composé d'un halogénure de métal avec un tampon de mercure dans un gaz noble est contenu pour former un plasma émettant de la lumière à l'intérieur de celui-ci. Une antenne (10) est disposée dans un trou (11) s'étendant à l'intérieur du creuset de plasma pour transmettre au remplissage de l'énergie micro-ondes induisant un plasma. L'antenne comporte une connexion (12) s'étendant à l'extérieur du creuset de plasma pour le couplage à une source d'énergie micro-ondes (14), la source étant représentée schématiquement. Des détails d'une telle source et de moyens d'alimentation en énergie micro-ondes dans la connexion sont décrits dans la demande de brevet internationale WO2010/128301.
