THE VACUUM CHAMBER FOR THE SSRF STORAGE RING

The antechamber type vacuum chamber design is chosen in the SSRF storage ring. Each chamber will be machined from two thick plates of A5083-H321 aluminum alloy and welded at their perimeter. The design, manufacture and test of a 6-meter long vacuum chamber prototype has been successfully completed in the R & D period. The flatness of the chamber is 0.23 mm and the maximum error in the horizontal direction is 1.4 mm. The design and manufacture of the chamber is described in this paper.
