| Outline of Final Research Achievements |
Utilization of the interaction of very-short-pulse discharges and matters for plasma generation and acceleration is considered a significantly novel acceleration regime. With this regime, a wide range of operational modes of electrostatic/electromagnetic acceleration (high-Isp/high-thrust) can be expected. In this study, to demonstrate these characteristics, single-pulse discharge systems were developed and thrust performance with these systems were examined. With our conventional systems, it was impossible to actively control the passive discharge pulse generation after laser ablation plasma generation. To achieve the active control, a novel pulse generator was developed and tested. Moreover, thrust performance was examined for repetitive pulse operation modes, and the maximum measured specific impulse was 8,200 s (at repetition rate of 1 kHz).
