Our group members Mervi Mantsinen and Dani Gallart have participated in the paper “Efficient generation of energetic ions in multi-ion plasmas by radio-frequency heating”, currently available as Advance Online Publication on the Nature Physics website.
The paper describes a new technique for the efficient generation of high-energy ions with electromagnetic ion cyclotron waves in multi-ion fusion plasmas. The method is especially suited for strong wave absorption by a low number of resonant ions. This study has been a collaborative effort between EU and US scientists together with contributions from a large number of international institutions.
The potential of the method is demonstrated on the world-largest plasma magnetic confinement device, JET (Joint European Torus, Culham, UK), and the high-magnetic-field tokamak reactor Alcator C-Mod (Cambridge, USA). The results of this study demonstrate efficient acceleration of Helium-3 ions to high energies in dedicated hydrogen-deuterium mixtures.
