	SECRAL (Superconducting ECR ion source with Advanced design in Lanzhou) is a fully superconducting ECR ion source built in 2005 with an innovative solenoid-inside-sextupole structure. Since then it has delivered many highly-charged ion beams for HIRFL (Heavy Ion Research Facility in Lanzhou) at IMP (Institute of Modern Physics), such as Xe²⁷⁺，Kr¹⁹⁺，Bi³⁶⁺ and Ni¹⁹⁺, and its on-line operating time increases year by year. By January 2011, the operation time of SECRAL has totaled up to 5700 hours. The increasing demand for intensive highly-charged ion beams has lead to the continuous enhancement of the SECRAL. To meet the requirement for stable highly-charged metallic ion beams, double-frequency of 18 GHz + 24 GHz heating with an off-axis oven had been carried out in 2010. 60-80 euA of Bi³⁶⁺ were produced at microwave power of about 2 kW and had been delivered continuously to HIRFL for about 10 days without any breakdowns. A number of improvements were planned to further improve the long-term stability of metallic ion beams.

SECRAL (Superconducting ECR ion source with Advanced design in Lanzhou) is a fully superconducting ECR ion source built in 2005 with an innovative solenoid-inside-sextupole structure. Since then it has delivered many highly-charged ion beams for HIRFL (Heavy Ion Research Facility in Lanzhou) at IMP (Institute of Modern Physics), such as Xe²⁷⁺，Kr¹⁹⁺，Bi³⁶⁺ and Ni¹⁹⁺, and its on-line operating time increases year by year. By January 2011, the operation time of SECRAL has totaled up to 5700 hours. The increasing demand for intensive highly-charged ion beams has lead to the continuous enhancement of the SECRAL. To meet the requirement for stable highly-charged metallic ion beams, double-frequency of 18 GHz + 24 GHz heating with an off-axis oven had been carried out in 2010. 60-80 euA of Bi³⁶⁺ were produced at microwave power of about 2 kW and had been delivered continuously to HIRFL for about 10 days without any breakdowns. A number of improvements were planned to further improve the long-term stability of metallic ion beams.
