Design, Manufacturing and Welding of Aluminum Alloy UHV Chambers for Taiwan Photon Source

Article Preview

Abstract:

This paper describes the design, manufacturing and welding sequence for the aluminum alloy vacuum chamber for Taiwan Photon Source. The vacuum chamber composes of aluminum extrusion chamber of A6063 and BPM chamber of A6061 aluminum alloys. The straightness and flatness of these extrusion chambers are controlled under 0.1mm/m and 0.2mm/m, respectively. The BPM chambers are manufactured precisely in oil-free environment, which provide clean surface and a precise sealing surface after machining. All the components are assembled in pre-aligned support system through the welding process, and then the results show the straightness of < 0.15mm/m, flatness of < 0.3mm/m, and leakage rates of < 2 × 10-10 mbar‧l/sec. were achieved.
