英文摘要：

Two GEM detector systems were used for gain and spatial measurement respectively. GEM detector measured the X-ray energy spectrum of copper target, the energy resolution was 21.5%. 8 keV X-ray entered double GEM detector, the x direction position resolution was 64 μm, and y di- rection position resolution was 68 μm. After refining and extracting research achievements, GEM de- tector and X-ray imaging experiment was set up for the course of specialized experiment of nuclear and particle physics for undergraduates. Students finished a series of work, including particle detection, data acquisition and processing. The X-ray imaging characteristics of various samples were studied.
