Verification of global gyrokinetic simulation of low frequency mode excited by thermal plasma in spherical tokamak
Abstract A low frequency Alfven eigenmode in the ST40 spherical tokamak (ST) is found to be resonantly excited by thermal ions from global gyrokinetic GTC simulations. The analyses of phase-space resonances and wave-particle energy exchanges show that the B…
