Innovative plasma heating methods in compact magnetic traps and expected applications in multidisciplinary fields: Archaeometry, Nuclear Physics, Polymers Chemistry.

At INFN-LNS we have recently observed a non-linear growing of the energy content (manifested by huge emission of UV-X radiation) in a compact-size magnetic trap when the plasma is heated in off-resonance mode. Proofs about electromagnetic-to-electrostatic wave conversion have been collected through advanced plasma diagnostics techniques (e.g. 2D-resolved X-ray spectroscopy and microwave diagnostics tools). Plasma modelling has been in parallel improved, allowing a better comprehension of wave-to-plasma interaction and effects on the density and energy distribution function. These studies open the way to non-classical uses of such magnetic-traps not only as ion sources for particle accelerators but also in the field of Archaeometry (IBAM), Nuclear Physics (INFN), Polymers Chemistry (ICTP).
