Operation status of secral at IMP

SECRAL (Superconducting ECR ion source with Advanced design in Lanzhou) is an advanced superconducting ECR ion source built with an innovative solenoid-inside-sextupole structure in 2005. Since 2007, SECRAL has delivered a good variety of highly-charged ion beams to HIRFL (Heavy Ion Research Facility in Lanzhou), such as 129Xe27+,78Kr 19+,209Bi36+ and 58,64Ni 19+ etc., and its beam delivery time increased greatly year by year. So far up to July 2011, the beam delivery by SECRAL has totalled up to almost 8000 hours. To meet the increasing demands, further improvements are planned and undertaking to enhance the capability of SECRAL. Detail results and discussions are presented in this paper..
