Tritium Removal from Carbon Plasma Facing Components [PDF]

, 2003
Tritium removal is a major unsolved development task for next-step devices with carbon plasma-facing components. The 2-3 order of magnitude increase in duty cycle and associated tritium accumulation rate in a next-step tokamak will place unprecedented ...

High Heat Flux Interactions and Tritium Removal from Plasma Facing Components by a Scanning Laser [PDF]

, 2002
A new technique for studying high heat flux interactions with plasma facing components is presented. The beam from a continuous wave 300 W neodymium laser was focused to 80 W/mm2 and scanned at high speed over the surface of carbon tiles.

Study the erosion of Eurofer-97 steel with the linear plasma device GyM

Nuclear Materials and Energy, 2023
This work reports on the investigation of Eurofer-97 erosion behaviour when exposed to the deuterium plasma of the linear device GyM. The erosion dependence of Eurofer-97 on the deuterium ion fluence, Φ≤2.3×1025 m−2, and temperature of the samples, T ...

Integrated modelling of the edge plasma and plasma facing components [PDF]

Journal of Nuclear Materials, 2007
Modelling of the interaction between the edge plasma and plasma facing components (PFCs) has tended to place more emphasis on either the plasma or the PFCs. Either the PFCs do not change with time and the plasma evolution is studied, or the plasma is assumed to remain static and the detailed interaction of the plasma and the PFCs are examined, with no ...

Plasma-surface interaction in the stellarator W7-X: conclusions drawn from operation with graphite plasma-facing components

, 2022
W7-X completed its plasma operation in hydrogen with island divertor and inertially cooled test divertor unit (TDU) made of graphite. A substantial set of plasma-facing components (PFCs), including in particular marker target elements, were extracted ...

Tungsten fibre-reinforced composites for advanced plasma facing components

Nuclear Materials and Energy, 2017
The European Fusion Roadmap foresees water cooled plasma facing components in a first DEMO design in order to provide enough margin for the cooling capacity and to only moderately extrapolate the technology which was developed and tested for ITER.

Assessment of plasma power deposition on the ITER ICRH antennas

Nuclear Materials and Energy, 2021
Ion cyclotron resonance heating (ICRH) is one of the three additional heating schemes to be deployed on ITER. Its two antenna arrays, installed on the outboard midplane, will deliver 20 MW of RF power in the 40–55 MHz frequency range.

Fusion tritons and plasma-facing components in a fusion reactor [PDF]

, 2007
We would like to discuss the role that 1 MeV tritons produced in deuterium$\hbox{--} $deuterium fusion reactions might play in a long-pulse or steady-state fusion reactor.
