Abstract: Synchrotron radiation is electromagnetic radiation that is emitted along the tangential direction of the motion orbit when electrons make circular or snaking motion at a speed close to the speed of light. It is also called light. This radiation covers a wide band from infrared rays to hard X-rays, and has excellent characteristics such as high brightness and good coherence. Especially in the soft X-ray and hard X-ray bands, synchrotron radiation source is the only source with both high brightness and free choice of wavelength. It provides a highly sophisticated experimental tool for studying the interactions between atoms or molecules and highenergy photons, thus opening a new door to the analysis of the microscopic world. In this paper, the key elements of synchrotron radiation are analyzed in the process of its production and utilization, and the latest progress of synchrotron radiation in atomic and molecular physics is reviewed.
