Abstract:

A report is given of preliminary experiments using a plasmascope to investigate the transverse motion of plasma in a discharge with a hot cathode in a longitudinal magnetic field. It was determined that in the presence of a critical magnetic field a plasma jet is formed steadily revolving in the ionic direction. The form of the jet and the period of rotation depend on the magnetic field intensity. Comparison of oscillograms revealed that pressure and magnitude of the discharge current also essentially affect the form of the jet. With the help of the plasmascope thus far only a discharge in hydrogen was studied, mainly for the purpose of testing and adjusting the new method. Hence some discrepancies and contradictions were noted. One obvious conclusion, however, is that the observed processes of transverse motion do not have anything in common with diffusion, but are a manifestation of the instability of the configuration of the plasma.
