The HIRFL-CSR vacuum system progressed steadily during the past year.The 2/3rd of CSR injection beam line (SSC-CSRm)’s vacuum chambers were installed in site in Jan. 2003 (Fig.1). The beam diagnostic devices were inserted in the chambers as well. The pressures in unbaked section were kept in 1-5×10-7 Pa range and in baked section were 2-5×10-9 Pa.
The HIRFL-CSR vacuum system progressed steadily during the past year. 2 / 3rd of CSR injection beam line (SSC-CSRm) ’s vacuum chambers were installed in site in Jan. 2003 (Fig.1). The beam diagnostic devices were inserted in the chambers as well. The pressures in unbaked sections were kept in 1-5 × 10-7 Pa range and in the baked sections were 2-5 × 10-9 Pa.
