The JYFL 18 GHz ECR ion source (HIISI) has been designed and constructed by the JYFL ion source group. The source was constructed in our own workshop, but the main components were obtained commercially. The first plasma in the source was on 10.4.2017, and the commissioning was started in September, 2017.
