Tyshchenko // Journal of Plasma Physics. - 2026. - Vol. 92, Issue 2. - Article number E54. - https://doi.org/10.1017/S0022377826101615https://doi.org/10.1017/S0022377826101615https://ekmair.ukma.edu.ua/handle/123456789/39865Momentum transport caused by spatial channelling – spatial transport of the energy of energetic ions by eigenmodes destabilised by these ions – is considered. The torques that result from the resonant interaction of trapped and passing energetic ions with an eigenmode are calculated and compared. The shearing rate of the toroidal flow that arises when an eigenmode transports toroidal angular momentum from the excitation region to the damping region is evaluated. The possibility that this flow can contribute to turbulence suppression is discussed.en-USfusion plasmaplasma flowsplasma instabilitiesarticleArticle
