JYFL 6.4 GHz ECRIS

The JYFL 6.4 GHz ECR ion source was built together with the K130 cyclotron  in 1991 for the nuclear physics program at the Department of Physics, University of Jyväskylä. The ion source is similar to the 6.4 GHz RT-ECRIS at the National Superconducting Cyclotron Laboratory at Michigan State University NSCL/MSU. The source has been upgraded twice, during 2001-2002 and 2005. First upgrade changed the configuration to a single stage mode and the second upgrade added a modified multipole structure (MMPS).
