Updates on the Storage Ring Vacuum System for Spring-8-II | |
|
||
| At SPring-8, aiming at the realization of upgrade project (SPring-8-II), development of hardware in each sub-system has been energetically advanced. Furthermore, a test half-cell construction is underway and scheduled for completion in this summer, so that interference between sub-systems and consistency in the alignment strategy could be confirmed. As for the vacuum system, development of a 12-m-long integrated vacuum chamber (12m-LIC) made of stainless steel and discrete photon absorbers with compact design are important keys to the success. The straight chamber was fabricated from several parts, mainly formed by roll-forming, and unitized by means of LBW according to proper longitudinal sections. Then, they will be integrated into the 12m-LIC with the bending chamber, photon absorbers and other vacuum components including transport gate valves at both ends. There are two kinds of photon absorbers, horizontal and vertical insertion types, both of which are equipped with scattering blocking structure. The configuration of the absorbing body was designed so as not to generate the plastic deformation with the heat transfer coefficient distribution calculated by CFD analysis. | ||
