| 内容記述 | A relaxation even known as “sawtooth crash” is simulated in a large tokamak plasma with monotonic safety factor close to unity. The domain and the time scale of the event are set to match observations. The simulation follows passive alpha particles with energies 35 keV-3.5 MeV, whose initial density peak is localized in the relaxing domain. While the 35 keV profile flattens, a synergy of multiple physical factors allows the 3.5 MeV profile to remain peaked, facilitating the use of benign sawtooth activity in a fusion reactor to expel helium ash while preserving good confinement of fast alphas. | |||||
