[en] The analysis of electromagnetic kinetic toroidal eigenmodes for general magnetohydrodynamic (MHD) equilibria has been extended to include the effects of non-Maxwellian equilibrium distribution functions. This is necessary to properly represent the response of the hot beam-ion species produced during neutral beam injection heating and the response of the alpha-particle species in a thermonuclear plasma. The influence of these components on low-frequency tokamak microinstabilities is investigated for realistic cases typical of the PLT and PDX experiments
