Impact of beryllium surface layers on deuterium retention in tungsten
In ITER mixed Be/W layers are likely to form and their retention behavior is unknown. A series of ITER-grade tungsten samples have been exposed in PISCES-B to deuterium plasma at 300oC, with and without beryllium impurity seeding of the plasma. If the beryllium concentration is small, the majority of the incident beryllium is re-eroded from the sample surface and only a few nm thick layer of mi...
متن کاملAn empirical scaling for deuterium retention in co-deposited beryllium layers
Different mechanisms will contribute to tritium retention in ITER, amongst which co-deposition with materials from the plasma-facing components may be the main contributor. A systematic study of the influence of the deposition conditions (substrate temperature, deposition rate, energy of the incident particles) on the deuterium retention in co-deposited beryllium layers has been carried out in ...
متن کاملDeuterium Retention in Carbon, Beryllium, and Carbon Layers on Titanium and Beryllium
In the context of plasma-facing walls in future nuclear fusion devices, a knowledge of the reaction mechanisms and properties of these materials is essential for operation and safety. The aim of the studies for this thesis was to investigate the effect of implanting ke V deuterium ions in various mixed and pure materials. To do so required an adaptation of the existing ultra-high vacuum experim...
متن کاملHigh-density Suspensions Formed under Waves
We performed a series of laboratory experiments to investigate the interactions of a turbulent wave boundary layer with a predominantly silt-size sediment bed. Quasi-steady, turbulent, highdensity suspensions (HDS) formed over a wide range of wave conditions and had near-bed (;1 mm above bed) concentrations ranging from 17 to 81 g/l scaling roughly with the wave orbital velocity. HDS were defin...
متن کاملHigh Density Plasma Deposition Modeling Using Level Set Methods
Several silicon dioxide chemical vapor deposition processes using high density plasma sources have been recently proposed in the literature [11, 7] for deposition of self-planarizing inter-level dielectric deposition. All these processes exhibit the competitive effect of simultaneous deposition and etching mechanisms. This paper describes the use of a robust simulation technique that can includ...
