Diagnostic Development for ST Plasmas on NSTX [PDF]

, 2003
Spherical tokamaks (STs) have much lower aspect ratio (a/R) and lower toroidal magnetic field, relative to tokamaks and stellarators. This paper will highlight some of the challenges and opportunities these features pose in the diagnosis of ST plasmas on

Ohmic Flux Consumption During Initial Operation of the NSTX Spherical Torus [PDF]

, 2000
The spherical tokamak (ST), because of its slender central column, has very limited volt-second capability relative to a standard aspect ratio tokamak of similar plasma cross-section.

ECRH/EBWH SYSTEM FOR NSTX-U [PDF]

, 2012
The National Spherical Torus Experiment Upgrade (NSTX-U) will operate at an axial toroidal field of up to 1 T, about twice the field available on NSTX. A 28 GHz electron cylotron resonance heating (ECRH) system is currently being planned for NSTX-U.
