SSRF is the first third generation light source in China. The storage ring vacuum system will adopt SS 316LN chambers with antechambers and discrete absorbers. Several chamber models using SS 316L were developed. There are three types of absorbers. TSP and (SIP+NEG) combined pumps will be used. A model of (SIP 2001/s+NEG WP1250) was developed. The vacuum system in total cell will be pre-baked before installing, then in-site baking will not be adopted. RF shielded bellows containing a single finger shielding structure and the high precision BPM section have been designed.
