Experimental studies on the X-radiation from a high-intensity annular discharge; Etudes experimentales sur le rayonnement X d'une decharge annulaire a forte intensite

Abstract

Under certain conditions, a very penetrating X-radiation is emitted at the start of a stabilised annular discharge. A number of experimental observations have been made using a pyrex toroid filled with deuterium or argon. The value of the stabilising magnetic field and the pressure have a very important influence on the intensity of the X-radiation emitted. The placing of an obstacle such as a magnetic mirror at a point of the torus can prevent the acceleration of runaway electrons during successive revolutions, and X-ray emission disappears.

Un certain nombre d'observations experimentales ont ete faites a l'aide d'un tore en pyrex rempli de deuterium ou d'argon. La valeur du champ magnetique stabilisateur et la pression jouent un role tres important sur l'intensite du rayonnement X emis. La disposition d'un obstacle tel qu'un miroir magnetique en un point du tore peut empecher l'acceleration d'electrons decouples au cours de revolutions successives et l'emission de rayonnement X disparait.
