Measurement of optics for the SSRF storage ring in commissioning

The Shanghai Synchrotron Radiation Facility(SSRF)is a low emittance third-generation synchrotron radiation light source.Some optics parameters of the storage ring were measured when commissioning.This report presents the common methods for measuring some optics parameters of the storage ring,including the betatron tune,beta function,chromaticity,natural chromaticity and dispemion.The results and analysis of measurement for the optics parameters are given here,which are indispensable for the orbit correction of the accelerator and the nonlinear optimization.
