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).

Abstract: The structure of currents and electric fields in the edge tokamak plasma is analysed for detached regimes of a tokamak. Strong electric fields in the divertor regions and near the X‐point are typical for detached regimes. It is shown that the value of the poloidal electric field in the regions with the temperature 1–2 eV is determined by the Spitzer conductivity and parallel currents. The latter are a combination of thermal and Pfirsch–Schlüter (PS) currents. The E × B drifts have a significant impact on the distribution of the plasma in the divertor. Stability of the detached regimes with strong electric fields is also analysed. It has been demonstrated that the so‐called PS instability caused by PS current can develop in the cold low‐temperature regions of the detached divertor.

Penetration of supersonic gas jets into a tokamak
TL;DR: In this paper, the evolution of a high-pressure supersonic jet is analyzed, and it is shown that an almost neutral jet can penetrate deep into the tokamak while a modest ionization degree should prevent its penetration for the case of low field side injection.

TL;DR: In this article, a new numerical solver for the B2.5 solver in SOLPS-ITER is presented, allowing the numerical grid to be extended to the true vessel boundaries.

TL;DR: In this paper, the possibility for pacing of type-I edge localized modes (ELMs) in H-mode plasmas by intermittent gas injection was investigated in ASDEX Upgrade as a possible alternative to, and in comparison with, ELM control by pellets.
