  SSRF is the first third generation light source in China. The storage ring vacuum system adopts SUS316LN material chambers with antechamber structure and discrete absorbers. There are several types of absorbers in the storage ring. TSP and SIP+NEG combined pumps are used. A single finger RF shielded structure is applied in bellows. The models of vacuum chambers (SUS316L material), absorbers and combined pumps (SIP 200l/s + NEG WP1250) were developed and tested. In order to check the vacuum system design and the fabrication technology, the model components were installed together with magnets and girders to forming a standard cell prototype.

  The engineering design of the mechanical system for the SSRF storage ring was finished. The first group components in each system, such as the magnets, vacuum chambers, BPMs, girders and other hardware, were fabricated and tested, respectively. In order to check the overall design and the installation procedure, a lattice cell prototype was installed by using these components. Based on it, the related utility system was installed and checked. The dynamic properties of the magnet-girder assembly were also tested in this prototype. Most of the design was confirmed during the installation, but still some problems were found. The modification for the overall design and some components design has been made before their mass production. The detail design and installation of the cell installation prototype and the test results are described in this paper.
