| Outline of Final Research Achievements |
We miniaturized a plasma wave receiver system onboard a spacecraft. The objective of the miniaturization is to realize plasma wave observations with high spatial resolutions. By miniaturizing the plasma wave receiver system, we can distribute a lot of plasma wave receivers in a target area. The miniaturization of the plasma wave receiver is realized by designing and developing an analog ASIC chip. The conventional plasma wave receiver consists of commercial discrete devices. However, the ASIC is the special device, which is dedicated only to plasma wave receivers. By using the ASIC of the plasma wave receiver, we developed the smallest plasma wave receiver in the world. Furthermore, we also succeeded in developing a small sensor probe using the ASIC of the plasma wave receiver. The sensor probe carries a electric field sensor made of the CFRP, a small communication wireless device as well as the ASIC. The sensor probe has the capabity to realize multiple point observations in space.
