The broadening of SOL profiles in JET tritium plasma and its impact on machine operation

Nuclear Fusion, 2022
Unusually high power loads on the beryllium limiter caused by neutral beam re-ionisation, and much cooler divertor target surfaces were observed during the recent JET tokamak tritium campaign.

MOLECULAR DYNAMIC SIMULATION OF PLASMA MATERIAL INTERACTION TO CALCULATE THEORETICAL SPUTTERING YIELD

Eurasian Physical Technical Journal, 2023
In a fusion reaction two light nuclei, Deuterium and Tritium merge to form a single heavier nucleus Helium. However, two positive nuclei repel each other. In order to merge two nuclei they need to have very high velocities.

Validation of the plasma-wall self-organization model for density limit in ECRH-assisted start-up of Ohmic discharges on J-TEXT

Nuclear Fusion, 2023
A recently developed plasma-wall self-organization model (Escande et al 2022 Nucl. Fusion 62 026001) predicts a significantly enhanced density limit, which may be attainable in tokamaks with ECRH-assisted Ohmic start-up and sufficiently high initial ...

PLASMA-WALL INTERACTIONS [PDF]

, 1977
Experimental and theoretical studies have been carried out to provide information on important phenomena occurring when a hot, dense plasma containing a transverse magnetic field is brought into sudden contact with a cold metal wall. Computational simulation has been used to study the physics of the fusion plasma boundary layer which forms at the ...

Global SOLPS-ITER and ERO2.0 coupling in a linear device for the study of plasma–wall interaction in helium plasma

Nuclear Fusion, 2023
Plasma–wall interaction (PWI) is a great challenge in the development of a nuclear fusion power plant. To investigate phenomena like erosion of plasma-facing components, impurity transport and redeposition, one needs reliable numerical tools for the ...

Plasma edge and plasma-wall interaction modelling: Lessons learned from metallic devices

Nuclear Materials and Energy, 2017
Robust power exhaust schemes employing impurity seeding are needed for target operational scenarios in present day tokamak devices with metallic plasma-facing components (PFCs). For an electricity-producing fusion power plant at power density Psep/R>15MW/

Integrated modelling: Coupling of surface evolution and plasma-impurity transport

Nuclear Materials and Energy, 2020
During the interaction of the scrape off layer (SOL) plasma with the first wall the evolution of both wall and plasma are tightly coupled: The erosion of the first wall leads to an impurity concentration in the plasma which affects the particle and power
