| Outline of Final Research Achievements |
This research is to propose a new, high-power electric propulsion system for the future advanced missions such as manned Mars exploration and asteroid exploration. We studied the feasibility and fundamental research as to the combination of high-density plasma by helicon-wave and inductive acceleration without applied magnetic fields and obtained the following results. 1) We succeeded to generate high-density plasma using a cusped-magnetic field in a low-aspect-ratio chamber, which is suitable for the electric propulsion application. The maximum density reached to 10 to the 19th power in cubic meters. 2) We simulated the final configuration of our proposal by a pulsed acceleration using a pulsed forming network, and we succeeded to estimate the plasma impedance which is inevitable for the steady state acceleration.
