The motion of dust particles near electric probe
Keywords:
dusty plasma, electric probe, model behavior of the particleAbstract
In the present work the dynamics of dust particles near electric probe in gas discharge at different pressures was studied. Trajectories of dust particles near electric probe with taking into account of the ion drag force and neutral friction force were calculated numerically. The comparisons between experimental and calculated results showed the good agreement.
