Abstract

Chalumeau à plasma produisant un arc de plasma entre un embout et un objet à chauffer. Une cathode thermionique est utilisée en tant qu'électrode pour fixer un point de cathode, la vitesse de l'arc de plasma dans le sens de l'axe est supprimée à un degré produisant une condition magnétiquement instable, et on fait tourner, tourner en sens inverse ou vibrer le chalumeau à plasma afin d'accroître la densité d'énergie et la capacité.
