The MHD Stability of Global Modes and Fast Particle Confinement in a Quasi-Axisymmetric Tokamak–Stellarator Hybrid

— The compatibility of global MHD modes stability and good collisionless confinement of fast particles is studied in a quasi-axisymmetric tokamak–stellarator hybrid. It is shown that both of these requirements can be satisfied at a relative plasma pressure up to ⟨β⟩ 0.02.
