Abstract

a. Dispositif pour produire un jet de plasma b. Ce dispositif comprend deux anodes espacées et placées de façon que, si on prolonge leurs axes ceux-ci se coupent suivant un certain angle, et une cathode qui est décalée du plan formé par le prolongement des axes des deux anodes, ce dispositif formant une colonne de gaz ionisés ayant la forme d'un Y inversé, en produisant ainsi une zone d'excitation stable. c. Spectrométrie.
