Research experiments on striction; Etudes experimentales sur le phenomene de striction

Abstract

Research work presented herewith concerns the behaviour of high intensity discharges in low pressure gases and examines the means of using the associated electromagnetic forces to heat the ionized gas and to avoid at the same time the cooling of the gas through contact with the walls of the chamber. We tried to stabilize the discharges by means of the combined action of a longitudinal magnetic field and of eddy currents induced in a conducting sheath. Devices for straight line and toroidal discharges have been tested. Research has been conducted with the aid of measurements of electric magnitudes, of penetrating radiations (x-rays, neutrons), and optical properties. The deformations of the luminous column have been followed by ultra rapid cinematography, whereas the evolution of the optical spectrum with time provided a monitor of the physical state of the plasma at any time.

La stabilisation des decharges a ete recherchee par l'action conjuguee d'un champ magnetique longitudinal et des courants de Foucault induits dans une enveloppe conductrice. Des dispositifs de decharges rectilignes et toroidales ont ete essayes. Les moyens d'investigation ont comporte des mesures de grandeurs electriques, des mesures de rayonnements penetrants (rayons X-neutrons) et des mesures optiques. Les deformations de la colonne lumineuses ont ete suivies par cinematographie ultra-rapide tandis que l'evolution du spectre optique au cours du temps a permis de controler, a chaque instant, l'etat physique du plasma.
