The density gradient in low pressure expanding plasmas creates an electric field that accelerates positive ions out of the plasma. Generally, the total potential drop is similar to that of a wall sheath allowing the plasma electrons to neutralise the ion beam. An expansion dominated by a magnetic field can result in the formation of electric double layers which produce a very directed neutralised beam of ions. Applications of these phenomena can be found in satellite electric propulsion (ion… CONTINUE READING
