Abstract: X ray photoelectron spectroscopy (XPS) is one of the most important methods for the qualitative and semi quantitative analysis of surface elements. It is an essential tool for the scientific research in surface analysis. How to improve the efficiency of the use of the instrument is a thorny problem. The opening and sharing of large-scale instrument to optimize the test efficiency has been proposed. In this paper, the experience of the opening usage of XPS is summarized.
