Title (EN) PLASMA STREAM GENERATOR WITH A CLOSED-CONFIGURATION ARC
(FR) GENERATEUR DE FLUX DE PLASMA D'ARC DE CONFIGURATION FERMEE
Abstract:
(EN) A plasma stream generator with a closed-configuration arc for achieving a stream comprising a central area at a uniform or very low temperature. The generator comprises a higher or even much higher number of electrode pairs than is usual, whereby rows may be formed and, in particular, an elongate stream, i.e. a curtain, may be achieved. The orientation problems resulting from the closeness of the jets and the increased attraction/repulsion therebetween are solved by means of magnetic devices (coils) of which there are generally three for a pair of electrode chambers.
(FR) Le générateur de flux de plasma est du type à arc de configuration fermée permettant d'obtenir un flux comportant une zone centrale de température uniforme ou surbaissée. Il comporte un nombre de paires d'électrodes plus élevé, voire nettement plus élevé, que l'ordinaire de manière à permettre la constitution de rangées et surtout la réalisation d'un flux de forme allongée, soit un rideau. Les problèmes d'orientation résultant de la proximité des jets et de leur attraction/répulsion accentuée sont réglés au moyen de dispositifs magnétiques (bobines), en général au nombre de trois pour une paire de chambres à éléctrodes.
