Abstract :
Studying the interaction of plasma and materials is very important in many plasma systems including those used in material processing applications, electric propulsion thrusters, or (bio-) surface treatment systems. For example, in the electric propulsion field, plasma-wall interactions influence thruster lifetime due to ion beam sputtering of the channel, and secondary electron emission can affect the sheath potential structure and plasma discharge conditions1. A better understanding of plasma-wall interactions will aid many practical plasma applications.
