At first I was thinking that a modified dpf could act as the ion source to accelerate the plasma to go through the magnet. Then I decided that maybe a railgun would be cheaper and easier to make. The power supply would not be as expensive as for a dpf because the rise time is not as critical. Tabletop systems could be made in university labs to test the concepts. The small dpf machines at university physics labs that are used to train fusion scientists would be ideal for testing.
