Tungsten has been chosen as one of the most promising candidates as the plasma-facing material in future fusion reactors.Although tungsten has numerous advantages compared with other materials,issues including dust are rather difficult to deal with.Dust is produced in fusion devices by energetic plasma-surface interaction.The re-deposition of dust particles could cause the retention of fuel atoms.In this work,tungsten is deposited with deuterium plasma by hollow cathode discharge to simulate the dust production in a tokamak.The morphology of the deposited tungsten can be described as a film with spherical particles on it.Thermal desorption spectra of the deposited tungsten show extremely high desorption of the peak positions.It is also found that there is a maximum retention of deuterium in the deposited tungsten samples due to the dynamic equilibrium of the deposition and sputtering process on the substrates.
