TL;DR: A review of recent advances in the area of MHD stability and disruptions, since the publication of the 1999 ITER Physics Basis document (1999 Nucl. Fusion 39 2137-2664), is reviewed in this paper.

TL;DR: In this article, an effective electron density equal to 24% of the critical density has been reached after injection of 3.3?bar?l of neon, but the resultant large plasma density is very poloidally and toroidally asymmetric; this implies that several valves distributed around the plasma periphery become necessary at this level of massive gas injection to ensure a homogeneous density distribution.

TL;DR: In this article, a massive injection of impurity gas into a plasma has been proved to reduce forces and localized thermal loads caused by disruptions in tokamaks, and this mitigation system is routinely used on ASDEX Upgrade to shut down plasmas with a locked mode.

TL;DR: Injection of impurity pellets has been shown to be a successful method of reducing thermal and mechanical loads during disruptions in ASDEX upgrade as discussed by the authors, and the requirements of such a method for mitigating disruptions in future devices are discussed.
