Research Abstract

Plasma dynamics in a magnetically expanding plasma including an electric double layer (DL) and its potential application to an electric propulsion device are investigated here. More efficient permanent magnet helicon plasma source is also developed and a generation of the large diameter ion beam is achieved. Further, the thrust imparted from a magnetic nozzle helicon plasma thruster is directly measured for the first time and compared with the theory.
