Circular magnetic accelerators can be configured to send high density neutral ion beams again a target up to 2.25 MeV. Actually Advanced Ignition is building the second circular accelerator system to be used in the Miranda reactor
They have a relative low cost structure that can be modified easily to increase power, density, add deviators and customized sensors.
Also can be used in junction to other Advanced Ignition accelerators to design particle colliders
They are designed to send up to 3e16 particles/shot again the target at 650keV. It is possible to increase ion energy up to 2.25MeV.
The advantage of high density beams is that it is possible to test how ionizing of arriving ions affect to the stopping power and damage on structures.
Also it is possible to generate large fusion reactions to be used in further tests.
