Abstract

A 2-D steady structure, which is the so-called strip, has been observed in a low-pressure radio-frequency discharge when applying a magnetic field perpendicular to the flow. The plasma parameters have been measured by means of a compensated Langmuir probe behind the magnetic barrier. Experimental outcomes reveal that the strip, which exists over a broad range of operating parameters, is a region of high electron density, temperature, and potential in comparison with the rest of the plasma medium.
