摘　　要：The physical properties of a solid are determined by the electrons near the Fermi energy and their low-lying excitations. Thus, it is crucially important to obtain the band structure near the Fermi energy of a material to understand many novel phenomena that occur, such as high-To superconductivity, density waves, and Dirac-type excitations. One important way to determine the Fermi surface topology of a material is from its quantum oscillations in an external magnetic field. In this article, we provide a brief introduction to the substation at the Synergetic Extreme Condition User Facility （SECUF）, with a focus on quantum oscillation measurements, including our motivation, the structure of and the challenges in building the substation, and perspectives.The physical properties of a solid are determined by the electrons near the Fermi energy and their low-lying excitations.
