| Outline of Final Research Achievements |
Recent observations with X-ray astronomy satellites reveal X-ray emission from planets, comets and satellites in the solar system. X-rays can be a new diagnostic tool to study various phenomena in the solar system such as particle acceleration in planetary magnetospheres and atmospheric escape from planets. We developed an original light-weight X-ray telescope based on MEMS (Micro Electro Mechanical Systems) technologies, aiming at in-situ X-ray imaging spectroscopy with exploration satellites. We demonstrated a sharp X-ray focusing with a newly fabricated Wolter type-I telescope. We proceeded to thermal and structural analyses for a micro astronomy satellite and conducted a vibration test with a test optic. No damage and change in dynamical response were identified after the vibration test. Furthermore, we tested a new micro X-ray mirror fabrication method using ion beam and succeeded to verify X-ray reflection for the first time in the world with this method.
