AbstractAbstract
[en] To increase the beam intensity of highly charged heavy ions for RIKEN RIBF project, we constructed and tested the RIKEN new SC-ECRIS. After producing the first beam in the spring of 2009, we tried to optimize the ion source condition for maximizing the beam intensity with 18 GHz microwave. We observed that the gentler field gradient and lager ECR zone size give higher beam intensity. Based on these studies, we produced 550 μA of Ar11+ and 350 μA of Ar12+ at the RF power of 1.8 kW. In this summer, we will try use the 28 GHz microwave to increase the beam intensity. (authors)
