THE VACUUM CHAMBER FOR THE SSRF STORAGE RING L.X.Yin, D.K.Jiang, H.W.Du, X.L.Jiang Shanghai National Synchrotron Radiation Center, P.O.Box 800-204, Shanghai 201800, P.R.China Abstract by the SR form severe challenge to the vacuum system designer. In order to deal with these loads, every step The antechamber type vacuum chamber design is including the general system design, the vacuum parts chosen in the SSRF storage ring. Each chamber will be design, the machine technique and the surface treatment machined from two thick plates of A5083-H321 should be executed strictly. Based on the practical aluminum alloy and welded at their perimeter. The design, requirements of the SSRF project, a prototype of the manufacture and test of a 6-meter long vacuum chamber vacuum chamber has been developed in the R D period prototype has been successfully completed in the R D in order to expose and solve the possible problems that period. The flatness of the chamber is 0.23 mm and the may be met during the construction. The prototype is maximum error in the horizontal direction is 1.4 mm. The shown in Figure 1. A series of standard on the chamber design and manufacture of the chamber is described in designing, machining, cleaning, welding and testing have this paper. been established. The necessary techniques have been
