摘要
SECRAL II is the second fully superconducting ECR ion source developed at IMP.It’s almost the duplicate of SECRAL,except for the cryogenic system[1].SECRAL II has integrated LHe recondensation system,which has the dynamic cooling capacity of more than 5 W.The main parameters of SECRAL I&II are shown in Table 1.The magnets of SECRAL II has been successfully fabricated and tested in 2015.In 2016,SECRAL II has been commissioned at 18 and 28 GHz with O and Xe ion beams,which has given very promising results.
