Reveal the site of particle acceleration in the Universe by using an X-ray imaging polarimeter

为了揭示宇宙中粒子加速的位置，我们制作了一台成像X射线偏振计。研制了一种新型空间用气体电子倍增器，并进行了环境试验。虽然在资助期内无法进行蟹状星云的气球观测，但我们在太空中建立了GEM操作方法，并完成了X射线偏振仪的研制。这些结果使我们与美国宇航局合作进行火箭实验和X射线偏振测量卫星GEMS。

To reveal the site of particle acceleration in the Universe, we have fabricated an imaging X-ray polarimeter. We manufactured a newly designed Gas Electron Multipliers (GEMs) for space use, and performed environment tests of them. Although we could not carry out the balloon observation of Crab Nebula during the grant period, we established the GEM operation method in space and completed the X-ray polarimeter development. Those results lead us to the collaboration works with NASA on a rocket experiment and the X-ray polarimetry satellite GEMS.
