In 2022,three on-line ion sources:SECRAL-IILECR4 and LECR3 serviced for HIRFL-CSR accelerator facility normally all year round,and their service time are 4114.5,679 and 2941.5 h respectively,amounting to 7735 h.There are 22 kinds of ion beams delivered successfully,including 7 kinds of metallic ions,accounting for 39.5%of the total service time.In particular,intense pulsed 209Bi36+beams were produced with SECRAL-II ion source in afterglow mode and applied for the HIRFL-CSRm.Table 1 summarizes the main information about the ion beams delivered by these three ion sources.
