First results from the recently developed, high-performance next-generation 18GHz ECRIS-SECRAL

The recently developed SECRAL (Superconducting Electron Cyclotron Resonance ion source with Advanced design in Lanzhou) ion source is a high-performance next- generation ECR ion source. It is designed to produce high current, high charge state heavy ion beams for HIRFL (Heavy Ion Research Facility in Lanzhou) cyclotrons. In August 2005, the first plasma was obtained at 18 GHz. Preliminary performances of SECRAL on gaseous elements such as oxygen, argon and xenon are quite promising, with many world record ion beams being delivered such as 2.3 emA O 6+ , 0.81 emA O 7+ , 0.81 emA Ar 11+ , 0.5 emA Xe 20+ , 306 eμA Xe 27+ and 9 eμA Xe
