Application of probing dusty particles to investigation of a stratified discharge with dusty plasma structures in a magnetic field

Experimental investigation of a stratified discharge in a magnetic field with the help of probe dusty particles falling through the discharge under the gravity force is described. The radial and azimuthal accelerations of probe particles in the stratum volume are measured. It is found that the particles move in the stratum without accelerations except in two regions. In the first region, the acceleration has two components directed toward the tube axis and upward, whereas, in the second region, they are directed toward the tube wall and downward.
