摘要
The National Spherical Torus Experiment (NSTX) is a low aspect-ratio fusion research facility whose research goal is to make a determination of the attractiveness of the spherical torus concept in the areas of high-P stability, confinement, current drive, and divertor physics. Remarkable progress was made in extending the operational regime of the device in FY 2002. In brief beta(t) of 34% and beta(N) of 6.5 were achieved. H-mode became the main operational regime, and energy confinement exceeded conventional aspect-ratio tokamak scalings. Heating was demonstrated with the radio-frequency antenna, and signatures of current drive were observed. Current initiation with coaxial helicity injection produced discharges of 400kA, and first measurements of divertor heat flux profiles in H-mode were made.
