Abstract
The concept of magnetic stabilization of thermally unstable gas discharges is based on sweeping nonuniformities in the E x B direction over a distance longer than the instability scale length in a time less than the instability growth time. About a decade ago, the technique was employed to stabilize DC-excited slab CO2 laser discharges at pressure levels of a few kPa. Meanwhile, Monte Carlo simulations indicated that scaling the magnetic stabilization technique to higher pressures - e.g. up to atmospheric pressure - would prove impractical due to a quadratic pressure dependence of the required magnetic field. The aim of this paper is to experimentally study the pressure scaling for a magnetically stabilized slab-shaped discharge in air. The lateral discharge velocity, as derived from voltage and current waveforms, is measured as a function of pressure and magnetic field strength. It is found that under certain conditions a uniform discharge can be obtained at pressures of several tens of kPa with magnetic fields of the order of 0.1 T.
