In addition to the operational limits imposed by MHD stability on plasma current and
pressure, an independent limit on plasma density is observed in confined toroidal plasmas …

A combination of recently installed state-of-the-art imaging and profile diagnostics, together
with established plasma simulation codes, are providing for the first time on Mega Ampère …

Edge shear flow and its effect on regulating turbulent transport have long been suspected to
play an important role in plasmas operating near the Greenwald density limit n G. In this …

Edge shear layer collapse causes edge cooling and aggravates radiative effects. This paper
details on the microscopic dynamics of the emergence of power (Q) scaling of density limit …

The fusion triple product depends on density, which is therefore a key parameter for the
future fusion reactor. In this paper the high density limit is studied in the reversed field …

Current-carrying, toroidal laboratory plasmas typically cannot be sustained with an electron
density above the empirical Greenwald limit. Presented here are tokamak experiments in the …

Multifaceted asymmetric radiation as well as strong poloidal asymmetry of the electron
density from the edge, dubbed as' MARFE', has been observed in high electron density …

The injection of a large amount of impurities is one of the possible ways of mitigating
disruption in large-scale tokamaks. The deposition of impurities at the center of the plasma is …

This article is dedicated to the characterization of turbulent transport in the scrape-off layer of
the Mega Ampère Spherical Tokamak [A. Sykes et al, Phys. Plasmas 8, 2101 (2001)] as a …

Multifaceted asymmetric radiation from the edge (MARFE) movement which can cause
density limit disruption is often encountered during high density operation on many …
