原始语种摘要: Previous measurements on the National Spherical Torus Experiment (NSTX) demonstrated peak, perpendicular heat fluxes, q dep,pk⩽15 MW m−2 with an inter-edge localized mode integral heat flux width, during high performance, high power operation (plasma current, I p = 1.2 MA and injected neutral beam power, P NBI = 6 MW) when magnetically mapped to the outer midplane. Analysis indicates that scales approximately as . The extrapolation of the divertor heat flux and λ q for NSTX-U are predicted to be upwards of 24 MW m−2 and 3 mm, respectively assuming a high magnetic flux expansion, f exp ∼ 30, P NBI = 10 MW, balanced double null operation and boronized wall conditioning. While the divertor heat flux has...
