Description
The Hefei Advanced Light Facility (HALF) is the fourth-generation synchrotron radiation light source based on Diffraction-limited Storage Ring (DLSR) with low beam emittance, high brightness and coherent photon flux. According to the physical design re-quirements of the HALF, the vacuum chamber struc-tural materials should have low outgassing rate, good electrical and thermal conductivity, high strength, and non-magnetic. CuZr and CuCrZr were selected as structural materials for the HALF storage ring vacuum chamber structural materials, taking into account ma-terial properties and manufacturing process. In this paper, thermal outgassing performances of CuZr and CuCrZr alloy pipes under temperature rise was inves-tigated for the design and calculation of HALF vacuum systems.
