Outline of Final Research Achievements |
Recently, the miniaturization of the instruments onboard scientific satellites is required because of the diversification of observation targets and the use of microsatellites. In this study, we propose a miniaturized plasma wave instruments for both waveforms and spectrum using an Application-Specific Integrated Circuits (ASICs) with variable frequency characteristics to further reduce the size of the plasma wave instruments, and we developed the ASIC for the new plasma wave instruments. The size of the developed circuit is 1.2 mm x 3.0 mm per component, and the required performance has been verified by circuit simulation. This research will enable us to significantly reduce the size of plasma wave instruments, which were previously large.

Academic Significance and Societal Importance of the Research Achievements |
本研究により、研究代表者らが提案している新型プラズマ波動観測器の実現にあたって特に重要である専用集積回路の設計を完了することができた。新型プラズマ波動観測器は従来の観測器と比べ大幅に小型化が可能であり、今後より増えると考えられる多点同時観測ミッションの実現には不可欠なものである。これは、プラズマ波動の多点同時観測を実施し、これまでに解明できなかった宇宙における電磁現象を理解することに大きく貢献するものである。
