1 HIRFL operationAfter almost one year shutdown for upgrading the vacuum chamber of the intector SFC, SFC has been in operation separately since May 2003. The SFC operation statistics and the accelerated beams from May to December 2003 are shown in Table 1 and 2. The main cyclotron SSC has been still shut down in 2003 for upgrading the SSC power supply system, control and diagnostic system, and the main experimental area. LECR3, an ECR ion source dedicated for atomic physics and surface physics research, has provided 2488 hours beams for experiments of atomic physics research.
