我们开发了一个结合背照式互补金属氧化物半导体（CMOS）成像传感器和Xilinx Zynq片上系统（SoC）设备的系统，用于太阳的软X射线（0.5-10 keV）成像光谱观测，以研究日冕的动力学。由于日冕中能量释放现象的典型时间尺度最多跨越几分钟，我们的目标是获得相应的能谱并导出物理参数，即，每几十秒或更短时间测量一次温度和辐射，以便将来进行太阳X射线观测。每秒几百帧或更高帧率的X射线光子计数技术可以实现这样的结果。我们使用Zynq SoC器件来实现这些要求。Zynq包含一个ARM处理器核心，也被称为处理系统（PS）部分，以及一个可编程逻辑（PL）部分。我们分别使用PL和PS来控制传感器和将数据无缝记录到存储系统。我们的目标是使用该系统的聚焦光学太阳X射线成像仪（FOXSI-3）探空火箭实验的第三次飞行的第一个光子计数X射线成像和光谱的太阳。(C)2017爱思唯尔B.

We have developed a system combining a back-illuminated Complementary-Metal-Oxide-Semiconductor (CMOS) imaging sensor and Xilinx Zynq System-on-Chip (SoC) device for a soft X-ray (0.5-10 keV) imaging spectroscopy observation of the Sun to investigate the dynamics of the solar corona. Because typical timescales of energy release phenomena in the corona span a few minutes at most, we aim to obtain the corresponding energy spectra and derive the physical parameters, i.e., temperature and emission measure, every few tens of seconds or less for future solar X-ray observations. An X-ray photon-counting technique, with a frame rate of a few hundred frames per second or more, can achieve such results. We used the Zynq SoC device to achieve the requirements. Zynq contains an ARM processor core, which is also known as the Processing System (PS) part, and a Programable Logic (PL) part in a single chip. We use the PL and PS to control the sensor and seamless recording of data to a storage system, respectively. We aim to use the system for the third flight of the Focusing Optics Solar X-ray Imager (FOXSI-3) sounding rocket experiment for the first photon-counting X-ray imaging and spectroscopy of the Sun.
