TL;DR: The National Spherical Torus Experiment (NSTX) has explored the effects of shaping on plasma performance as determined by many diverse topics including the stability of global magnetohydrodynamic (MHD) modes (e.g., ideal external kinks and resistive wall modes), edge localized modes (ELMs), bootstrap current drive, divertor flux expansion, and heat transport.

TL;DR: In this paper, the edge localized modes (ELM) using resonant magnetic perturbation have been demonstrated for toroidal mode numbers n = 3, 4, 6 with an ELM frequency increase by up to a factor of 9, compatible with pellet fuelling.

Interaction between a low-frequency electrostatic mode and resonant magnetic perturbations in MAST
TL;DR: In this article, a strong 10 kHz mode is detected in both potential and density fluctuations of the edge plasma of the MAST tokamak using a reciprocating probe, which is radially localized, with outer limit 2 cm inside the separatrix, and is affected on application of resonant magnetic perturbations generated by external coils.

TL;DR: The Mega Ampere Spherical Tokamak (MAST) programme is strongly focused on addressing key physics issues in preparation for operation of ITER as well as providing solutions for DEMO design choices, operating with smaller edge localized modes (ELMs), predicting and handling plasma exhaust and tailoring auxiliary current drive.
