Abstract:

Measurements were made concerning the initial breakdown of a gas subjected to an electrodeless discharge in a toroidal geometry with the magnetic field in the longitudinal direction. The current through a ring conductor embracing the toroidal discharge tub established the rotational transform required for plasma equilibrium. Smear photographs of the discharge were made, looking through the discharge tube in a plane which passes through the orus axis. Simultaneous measurements of ligh intensity and of the magnetic field in the gas show that the initial breakdown occurs at a time when the magnetic field is zero. The data allow an interpretation in which the plasma has the form of a shell. Marginal breakdown conditions have been measured. Author
