Tungsten melting and erosion under plasma heat load in tokamak discharges with disruptions

Nuclear Materials and Energy, 2017
Full tungsten poloidal and mushroom limiters were tested in series of experiments with disruptions in the T-10 tokamak. Significant melting, formation of small craters and erosion of the tungsten limiter have been observed after ∼400 discharges with ...

Dust remobilization from rough planar surfaces in tokamak steady-state plasmas

Nuclear Materials and Energy, 2018
The ability of tungsten (W) dust to be remobilized from rough tokamak plasma-facing surfaces is investigated in this study. Atomic Force Microscopy is used to evaluate the adhesion force distribution between W spheroids of ∼1−10 µm radius and a rough W ...

Thermal profiles and improved confinement accessibility in RFX-mod and TCV [PDF]

, 2013
Humans do not live by bread alone. Physically we are puny creatures with limited prowess, but with unlimited dreams. In the last few decades humankind reached the Moon (1969) and built airports over the sea (1994), but 925 million people are still under-

Modellazione di equilibri tokamak in RFX-mod verso RFX-mod2 [PDF]

, 2022
In questa tesi si sono studiati gli equilibri tokamak. Basandosi su scariche realizzate sperimentalmente e su simulazioni numeriche dell'evoluzione nel tempo delle stesse scariche si sono cercati degli equilibri.
