Exploration of the X-ray polarimetry astrophysics using rocket experiments

为了探索X射线偏振天体物理学，我们与美国宇航局戈达德太空飞行中心合作，开发了一种用于太空任务的X射线偏振仪。在实验室样机的基础上，设计并制作了X射线偏振仪。我们已经在布鲁克海文国家实验室的同步加速器设施中对旋光仪的性能进行了评估，并确认探测器满足我们的要求。我们还利用Geant4工具包开发了旋光仪的模拟器。通过调节模拟器，精确估计了旋光仪的背景和探测器的响应。

To explore the X-ray polarimetry astrophysics, we have developed an X-ray polarimeter for using space missions in collaboration with NASA Goddard Space Flight Center. The X-ray polarimeter is designed and fabricated based on the laboratory prototype detector. We have evaluated the performance of the polarimeter at the synchrotron facility in Brookhaven National Laboratory and confirmed that the detector satisfied our requirements. We also developed a simulator of the polarimeter with the Geant4 toolkit. By tuning the simulator, background and detector response of the polarimeter was precisely estimated.
