| Outline of Final Research Achievements |
This study aims to realize two-dimensional focusing imaging-spectroscopy in the soft X-ray band for solar flares in order to understand magnetic reconnection and particle acceleration. The key to this observation is a camera system using a back-illuminated CMOS sensor, which is sensitive to soft X-rays and capable of high-speed continuous exposure of several hundred times per second or more.
In this study, we installed our CMOS camera system on NASA's sounding rocket (FOXSI-3) and succeeded in soft X-ray focusing imaging-spectroscopy of the solar corona for the first time in the world, although during non-flare condition.
On the other hand, we have developed CMOS detector and camera system for future solar flare observations using a satellite, and successfully obtained the necessary basic technologies.
