Jin Chang have long been engaged in the detections and researches of gamma ray emission and high energy charged particles that come from outer space, and is one of the pioneers for studying space astronomy in China. He created and developed a new technique of detecting high energy cosmic ray electrons. This technique was used in a long-term balloon experiment (ATIC experiment) of America aiming at detecting cosmic rays in Antarctica. Based on the technique, he leaded the DAMPE (also called as “WuKong”) project as the chair scientist. The “WuKong” was successfully launched in December 17, 2019 and it is the very first satellite of China used for astronomical research. Also, this launch marked that China is leading the world at several key techniques and breakthrough on detecting the spectrum of cosmic ray electrons and protons. Furthermore, in order to response for the needs of the major national strategic, Jin CHANG and his team successfully developed gamma ray spectrometers for ShenZhou II, Chang’e I and II.
