Query: MHD stability of JT-60SA operation scenarios driven by passing energetic
  particles for a hot Maxwellian model   We analyze the effects of the passing energetic particles on the resistive
ballooning modes (RBM) and the energetic particle driven modes in JT-60SA
plasma, which leads to the prediction of the stability in N-NBI heated plasma.
The analysis is performed using the code FAR3d that solves the reduced MHD
equations describing the linear evolution of the poloidal flux and the toroidal
component of the vorticity in a full 3D system, coupled with equations of
density and parallel velocity moments for the energetic particle (EP) species
assuming an averaged Maxwellian EP distribution fitted to the slowing down
distribution, including the effect of the acoustic modes. The simulations show
the possible destabilization of a 3/2-4/2 TAE with a frequency (f) of 115 kHz,
a 6/4-7/4 TAE with f=98 kHz and a 6/4 or 7/4 BAE with f=57 kHz in the ITER-like
inductive scenario. If the energetic particle beta increases, Beta induced AEs
(BAE), Toroidal AEs (TAE) and Elliptical AEs (EAE) are destabilized between the
inner-middle plasma region, leading to the overlapping of AE of different
toroidal families. If these instabilities coexist in the non-linear saturation
phase the EP transport could be enhanced leading to a lower heating efficiency.
For a hypothetical configuration based on the ITER-like inductive scenario but
an center peaked EP profile, the EP beta threshold increases and several BAEs
are destabilized in the inner plasma region, indicating an improved AE
stability with respect to the off-axis peaked EP profile. In addition, the
analysis of a hypothetical JT-60SA scenario with a resonant q=1 in the inner
plasma region shows the destabilization of fishbones-like instabilities by the
off-axis peaked EP profile. Also, the EPs have an stabilizing effect on the
RBM, stronger as the population of EP with low energies (below 250 keV)
increases at the plasma pedestal.
