项目摘要

To guarantee human beings to work safely and effectively in the space, the forecast for strong solar flares is indispensable. And the study of the build-up and release mechanism of the magnetic field energy, which is the source of flares and solar plasm ejections, is essentially needed.To study the build-up and release mechanism of he magnetic field energy we need to measure the variations of the three dimensional structures of solar magnetic field over the full solar disk. The primary purpose of this research project is the construction of a good full-solar-disk vector magnetograph. We succeeded to construct the new Solar Magnetic Activity Research Telescope (SMART) at Hida Observatory, Graduate School of Science, Kyoto University form 2002 through 2003.In 2004, we made many test observation to examine the performance of the SMART and made many fine adjustment to optimize the power of the telescope. From these observation with SMART, we got the following results :(1)We confirmed the SMART achieves the best spatial resolution in the world in the full disk Halpha solar image. The better spatial resolution than 1 arc second is obtained over the full solar disk with the SMART.(2)We first succeeded to obtain the full disk solar vector magnetic field image with the SMART.(3)We succeeded in keeping the temperature inside of the telescope tubes to be in the range from 30 degrees to 20 degrees throughout a year in the atomospheric temperature variation from -17degrees (in winter) to 30 degrees (in summer) to stabilize the many kinds of optical elements in their best condition.We also succeeded in getting many new findings in the studies of mechanism of solar flare and solar plasm ejections called as Halpha surge by using the Hida Domeless Solar Telescope and Satellite instruments such as TRACE and SOHO, and we published these results in many papers which are summarized in a report book.

为了保证人类在太空中安全有效地工作，对太阳耀斑的预测是必不可少的。而作为耀斑和等离子体抛射源的磁场能量的建立和释放机制的研究是十分必要的，为了研究磁场能量的建立和释放机制，需要测量整个太阳盘面上磁场的三维结构变化。本研究项目的主要目的是建造一台性能良好的全日面矢量磁象仪。我们于2002 ~ 2003年在京都大学研究生院理学研究科希达天文台成功地建造了新的太阳磁活动研究望远镜（SMART）。2004年，我们对SMART进行了多次测试观测，并对望远镜的功率进行了多次微调。通过对SMART的观测，我们得到了以下结果：（1）我们证实了SMART在全圆盘Halalpha太阳图像中达到了世界上最好的空间分辨率。SMART在整个太阳盘面上获得了优于1角秒的空间分辨率。(2)We首次成功地用SMART获得了全圆盘太阳矢量磁场图像。(3)We在大气温度变化为-17度的情况下，成功地将望远镜管内的温度保持在全年30度至20度的范围内。（冬季）30度（夏季）使各种光学元件稳定在最佳状态，在太阳耀斑和等离子体抛射机制的研究中也取得了许多新的发现利用希达无顶太阳望远镜和卫星仪器如TRACE和SOHO，我们在许多论文中发表了这些结果，并在一本报告书中总结了这些结果。
