空间太阳高能辐射探测关键技术研究

High energy radiation detection of solar in space, as a major approach in observation of solar activity, is of great significance for research of solar physics and space environment. Since the first solar X-ray observing from rocket-based detectors in 1948, dozens of specific satellites or detectors had been launched into orbit for solar observation, followed by massive observing data and scientific gains. Chinese astronomy also carried out excellent solar observation through pick-up projects in other satellites such as Shenzhou-2 and CBERS-1, and will launch several satellites dedicated to solar observation according to “a study report on the future space science program in China”. This propose is aimed at requirements of future high energy radiation detection of solar in space, and focusing on three critical technologies: high count rate detection system, charge readout method in high dynamic range, pile-up detection and data compensation algorithm. By using charge measurement ASICs, improving readout circuits and data processing algorithm, a prototype solar radiation detection system could be achieved with high dynamic range in high count rate. This propose will gather experience in development of space instruments, and set the foundation for Chinese future solar observation projects in space.

空间太阳高能辐射探测，作为观测太阳活动的重要手段，在太阳物理研究领域和空间环境研究领域有着重要的意义，国际上自1948年利用火箭首次观测到太阳X射线以来，已经发射了几十颗专用的太阳观测卫星，取得了大量观测数据；我国虽然尚无专用的太阳观测卫星，但也利用资源一号，神舟二号等搭载机会，进行了太阳高能辐射和高能粒子的观测，并在空间科学中长期规划中也提出了多个太阳观测项目。本课题针对空间太阳高能辐射探测的需要，重点研究高事例率探测器系统、大动态范围电荷读出方法和信号堆积检测与修正补偿算法三项关键技术，通过使用集成电荷测量芯片、改进读出电路和数据处理方法的方式，实现高事例率大动态范围的太阳高能辐射探测系统原型，积累相关空间探测系统的研制经验，为将来我国的空间太阳观测项目打下基础。
