At present, the research on dark matter is the cutting edge of science. It is the hotspot to find out if the dark matter exist in the form of particle by observing the electrons and γ-rays resulted from the disintegration or reciprocity of dark matter. Emulsion chamber is a powerful detector for high-energy electrons and γ-rays with high special and energy resolution. As one of the payloads of ``ShiJian eight" satellite, the emulsion chamber detector is the first one in China designed for space observing the high-energy electrons and γ-rays. In this paper, several problems are discussed, such as the design principle of the detector, data analysis, process of designing and some results of this experiment. The design life of this detector is about 15 days in its orbit, and the energy range of the particle detected by the emulsion chamber is about 100GeV to 5 TeV.
