The JYFL 14 GHz ECR ion source is based mainly on the design of the 14 GHz AECR-U source at the Lawrence Berkeley National Laboratory. The source was constructed in our own workshop, but the main components were obtained commercially. The first plasma in the source was on February 21, 2000, and the source was commissioned in June 2000.

The ion source extraction was upgraded in two stages in 2013 and 2015.
