[Abstract]:Solar soft X-ray observation is an effective way to obtain the important parameters such as temperature density and velocity of motion of high temperature plasma. It is very important to study the heating mechanism and dynamic behavior of solar flare burst and evolution process. In this paper, based on the development requirement of high resolution solar soft X-ray spectrometer, combined with the domestic and foreign experience of solar soft X-ray discrete line observation and modern soft X-ray CCD technology, In this paper, a scheme of 1~10ke V soft X-ray discrete line detection by Bragg diffraction of curved crystal is presented, and a readout circuit system of soft X-ray CCD sensor is developed. This paper mainly introduces the electronic hardware and software design of the readout circuit system of soft X-ray CCD. The driving timing chip ADCDS1603 which is required by FPGA to produce CCD is used to convert the output signal of CCD to digital signal. The converted data is transmitted to the upper computer through USB interface and displayed in real time. The experimental results show that the proposed scheme meets the requirements of the electronic system of high resolution solar soft X-ray integrated spectrometer and realizes the function of CCD sensor readout system. In the end, the design and implementation of high resolution solar soft X-ray CCD sensor system are summarized, and the corresponding prospects for the improvement of readout circuit system are given.
