Modelling of Electron Cyclotron Resonance Ion Sources plasmas: a 3D full-wave plus kinetic approach to Charge Breeding

Not scheduled
ECR charge breeding technique


Dr David Mascali (INFN-LNS)


Numerical simulations are powerful tools for optimizing the wave-to-plasma interaction process in Electron Cyclotron Resonance Ion Sources. Several alternative methods of plasma heating like Frequency Tuning Effect (FTE) or Two Frequency Heating (TFH) can be exploited by a proper matching of the incoming RF power with the plasma electrons. This supports the increase of beam currents and charge states also in case of ECRIS-based Charge Breeders. The presentation will show an overview of the work on ECRIS modelling, carried out in the framework of the EMILIE Project by the INFN team. The impact of the resonator nature of the plasma chamber, the interplay between electrons and ion dynamics, and the overall impact on the beam properties will be discussed in details according to a step-by-step modelling of increasing complexity. The contribution will describe the several steps needed to achieve quasi-self-consistent results concerning the wave-to-plasma electrons coupling (made by matching a full-wave 3D approach to a collisional 3D kinetic code), based on a “cold plasma” approximation. A particular attention will be payed to modelling benchmarks coming from beam production or charge breeding experiments, and directly from plasma diagnostics tools.
