WebThe electrostatic sheath in a conventional dc discharge involving dusty plasmas is revisited. Assuming Boltzmann responses for electrons and dust particles and taking into account the effect of ion flows, it is shown that the sheath around an electrically floated cylindrical wire contains electrons and ions but no dust particles. WebIn this review, we summarize recent advances in the field of dusty plasmas at strong magnetic fields. Special emphasis is put on situations where experimental laboratory observations are available. These generally comprise dusty plasmas with magnetized electrons and ions, but unmagnetized dust.
