The National Spherical Torus Experiment (NSTX) has recently studied the use of a liquid lithium divertor (LLD). Divertor Langmuir probes have also been installed for making measurements of the local plasma conditions. A non-local probe interpretation method is used to supplement the classical probe interpretation and obtain measurements of the electron energy distribution function (EEDF) which ...

The extended perturbed equilibrium code asymptotic matching is used to simulate the triggering of n = 1 neoclassical tearing modes (NTMs) by a pulsed, rotating, 1, resonant magnetic perturbation (RMP) in two example NSTX discharges. Although discharges are significantly different from one another, results sets simulations quite similar. critical RMP pulse amplitude required trigger an NTM minim...

A new tangential 2D soft x-ray imaging system (SXRIS) has been designed for DIII-D to directly measure the edge island structure in the lower X-point region [1]. Plasma shielding and/or amplification of applied resonant magnetic perturbations (RMPs) may play a role in the suppression of edge localized modes (ELMs). Measurements of the actual island structure inside the plasma are needed to vali...

The dynamics of fast particles corresponding to keV in NSTX, or alpha a properly rescaled reactor-grade spherical tokamak, is computed numerically through integration the full equations motion. magnetic moment μ these has large oscillations, and even chaotic ones, sizable domain machine. This both practical physical consequences. First, when use guiding-center gyrokinetic calculations for such ...
