Comprehensive evaluation of the linear stability of Alfvén eigenmodes driven by alpha particles in an ITER baseline scenario
Figueiredo, A.C.A.; Rodrigues, P.; Borba, D.; Coelho, R.; Fazendeiro, L.; e.a. (IOP Publishing, 2016-06)The linear stability of Alfvén eigenmodes in the presence of fusion-born alpha particles is thoroughly assessed for two variants of an ITER baseline scenario, which differ significantly in their core and pedestal temperatures. ... -
Efficient generation of energetic ions in multi-ion plasmas by radio-frequency heating
Kazakov, Ye O.; Ongena, J.; Lerche, E.; Mantsinen, M. J.; Van Eester, D.; e.a. (Springer Nature, 2017-06)We describe a new technique for the efficient generation of high-energy ions with electromagnetic ion cyclotron waves in multi-ion plasmas. The discussed 'three-ion' scenarios are especially suited for strong wave absorption ... -
Sensitivity of alpha-particle-driven Alfvén eigenmodes to q-profile variation in ITER scenarios
Rodrigues, P.; Figueiredo, A.C.A.; Borba, D.; Coelho, R.; Fazendeiro, L.; e.a. (IOP Publishing, 2016-07)A perturbative hybrid ideal-MHD/drift-kinetic approach to assess the stability of alpha-particle-driven Alfv�n eigenmodes in burning plasmas is used to show that certain foreseen ITER scenarios, namely the MA baseline ...
