Plasma rotation in a plasma generator

ABSTRACT

The plasma rotation in a linear magnetic configuration has been investigated by means of high-resolution Doppler-spectroscopy. The effects of external device parameters and ion mass as well as the radial profiles have been studied. A simple model, based on the conservation of the total angular momentum, explains the main empirically determined dependences of the average angular velocity. The results are compared with the common multifluid description developed for hollow cathode discharges.
