项目摘要

The Astro-E satellite was launched on Feb. 10, 2000, trying to be the Japanese fifth X-ray astronomical satellite, but failed to be it according to an accident in its launcher. It was intended to be a international X-ray observatory in orbit having a capability for high sensitivity observations with the finest energy resolution ever achieved in a very wide energy range. A part of the scientific instruments were developed under a Japan-US collaboration, and the final completion of the development, the instrumental calibrations before launch, the final performance verification before the launch after mounting them in the spacecraft and so on were done in the latest two years. By this grant-in-aid, participation of Japanese members in the final completion and tests of the instruments in US, taking part of US members in the final integration tests in Japan, attendance of Astro-E team members in meetings for reviews and investigations on current issues and so on were supported!. The developments were performed collaboratively by all the Japan-US members and the aid by this budget was very useful. Furthermore, this development yielded new results on high-energy-photon detectors and presentations of them in international conferences were also supported. In parallel to those activities on the instrumental developments, investigations on how to maximize the scientific yields have been done by organizing a science working group composing of leading scientists from Japan, US and Europe. In particular, meetings on collaborations of the Astro-E project with the European Space Agency were held and participation of the team members were supported by this grant in the last fiscal year. Although the launch failed, the spacecraft development and the international collaborations were very fruitful.

Astro-E卫星于2000年2月10日发射，试图成为日本的第五颗X射线天文卫星，但由于发射器发生事故而未能成功。它打算成为一个国际轨道X射线观测站，具有在非常宽的能量范围内进行高灵敏度观测的能力，并具有有史以来最好的能量分辨率。部分科学仪器是在日美合作下开发的，最后完成开发、发射前的仪器校准、安装在航天器上后发射前的最后性能验证等工作都是在最近两年完成的。通过这笔补助金，日本成员参与了在美国的仪器的最后完成和测试，美国成员参加了在日本的最后集成测试，Astro-E团队成员参加了对当前问题的审查和调查会议等。开发是由所有日美成员合作进行的，该预算的援助非常有用。此外，这一发展在高能光子探测器方面取得了新的成果，在国际会议上介绍这些成果也得到了支持。在开展这些仪器开发活动的同时，还组织了一个由日本、美国和欧洲的主要科学家组成的科学工作组，对如何最大限度地提高科学产量进行了调查。特别是，举行了Astro-E项目与欧洲航天局合作的会议，小组成员的参与得到了上一财政年度赠款的支助。虽然发射失败，但航天器的研制和国际合作是非常富有成效的。
