In an electric propulsion system such as thruster, dust particles are generated because of
the thrusters' wall erosion, and these heavily charged dust particles affect the thrusters' …

A novel method for the in situ visualization and profilometry of a plasma-facing surface is
demonstrated using a long-distance microscope. The technique provides valuable in situ …

Ion-induced electron emission (IIEE) is an important process whereby ions impinging on a
material surface lead to net emission of electrons into the vacuum. While relevant for …

The Bohm sheath criterion is formulated by using Sagdeev potential approach for
