| Abstract: | The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is one type of high power advanced electrical propulsion developed from the controlled fusion concept. It features with high and variable specific impulse. The components of VASIMR and their working principle are introduced. Through analysis of the system efficiency and key technologies it is pointed that the key problems of designing a fine VASIMR are the development of high performance helicon wave plasma source and the improvement of the ICRH system efficiency. Finally the advantage of executing space tasks by VASIMR is evaluated. |
