Study of Aspect Ratio Effects on Kinetic MHD Instabilities in NSTX and DIII-D [PDF]

, 2004
We report general observations of kinetic instabilities on the low aspect-ratio National Spherical Torus Experiment (NSTX) and describe explicit aspect ratio scaling studies of kinetic instabilities using both the NSTX and the DIII-D tokamak.

Numerical assessment of the impact of the guiding-centre approximation on fast ion simulations in NSTX

Nuclear Fusion
Guiding-centre (GC) and full-orbit (FO) simulations of the beam-injected fast ion distribution and the corresponding neutron emissivity have been carried out for magnetohydrodynamics-quiescent National Spherical Torus eXperiment (NSTX) plasmas, using a ...

Precision metrology of NSTX surfaces using coherent laser radar ranging [PDF]

, 2000
A frequency modulated Coherent Laser Radar ranging diagnostic is being used on the National Spherical Torus Experiment (NSTX) for precision metrology. The distance (range) between the 1.5 {micro}m laser source and the target is measured by the shift in ...

Initial Results from Coaxial Helicity Injection Experiments in NSTX [PDF]

, 2001
Coaxial Helicity Injection (CHI) has been investigated on the National Spherical Torus Experiment (NSTX). Initial experiments produced 130 kA of toroidal current without the use of the central solenoid.
