1. HIRFL Operation HIRFL accelerator complex was fully in operation in 2004. The main cyclotron SSC has been operated since July, 2004 after some time shut-down for upgrading the SSC power supply system, control and diagnostic system, and the main experimental area. The statistics of HIRFL operation time and beams delivered from HIRFL in 2004 is shown in Tables 1 and 2 respectively. During HIRFL operation in 2004, beam intensity from SFC typically 1-10 eμA, and from SSC typically a few hundred enA, such as 22Ne10+ 70 MeV/u, about 500 enA.
