TLDR
The Experimental Advanced Superconducting Tokamak in Hefei, China, achieved this record pulse length by first confining the plasma using lithium-treated vessel walls, and then maintaining it with a so-called lower hybrid current drive as mentioned in this paper.Abstract:
A high-confinement plasma that is potentially useful for controlled fusion has now been sustained for over 30 s. The Experimental Advanced Superconducting Tokamak in Hefei, China, achieved this record pulse length by first confining the plasma using lithium-treated vessel walls, and then maintaining it with a so-called lower hybrid current drive.read more

TL;DR: In this paper, the main focus is on the main design driver, steady state power fluxes in the DT phases, obtained from simulations using the 2-D SOLPS-4.3 and SolPS-ITER plasma boundary codes, assuming the use of the low Z seeding impurities nitrogen (N) and neon (Ne).

Edge-localized-modes in tokamaksa)
TL;DR: In this article, the authors show that when the gradient in the H-mode transport barrier grows to exceed the MHD stability limit, the ELM instability grows explosively, rapidly transporting energy and particles onto open field lines and material surfaces.

Advances in H-mode physics for long-pulse operation on EAST
TL;DR: The experimental capabilities of EAST have been upgraded with the power enhancement (source power up to 26 MW) of the continuous-wave heating and current drive system, replacement of the upper graphite divertor with an ITER-like W monoblock divertor, and installation of a new internal cryopump in the upper divertor and a set of 16 in-vessel resonant magnetic perturbation (RMP) coils.
