TL;DR: In this article, the authors describe the response of plasma facing components manufactured with tungsten and CFC to energy loads characteristic of Type I ELMs and disruptions in ITER, in experiments conducted under an EU/RF collaboration in two plasma guns (QSPA and MK-200UG) at the TRINITI institute.

TL;DR: In this paper, the authors studied the plasma/material interaction in disruption simulation experiments at the plasma gun facility MK-200 UG, where graphite, tungsten and aluminium targets (beryllium-like material) were irradiated by intense plasma streams under heat fluxes typical for international thermonuclear experimental reactor (ITER) hard disruption.

TL;DR: In this article, the first disruption simulation experiment under plasma stream power density of 30-40 MW/cm2 is presented, where POCO and RGT graphite were exposed to perpendicular and inclined incidence of hydrogen plasma stream with energy density up to 1.4 kJ/cm 2, directed ion energy of 2-3 keV in the presence of magnetic field up to 3.3 T.

TL;DR: In this article, the evaporation threshold of carbon fiber composite, the velocity of carbon vapor motion along and across the magnetic field lines, and the parameters of carbon plasma such as temperature, density and ionization state are compared with the results of numerical modeling.

TL;DR: In this paper, it was shown that sudden evaporation of a thin material layer produces a cloud of vapor plasma, which acts as a thermal shield protecting the surface from further excessive eva-oration.
