  title = {Influence of tungsten microstructure and ion flux on deuterium plasma-induced surface modifications and deuterium retention},
  abstract = {The influence of surface temperature, particle flux density and material microstructure on the surface morphology and deuterium retention was studied by exposing tungsten targets (20\&$\#$xa0;μm and 40\&$\#$xa0;μm grain size) to deuterium plasma at the same particle fluence (1026\&$\#$xa0;m-2) and incident ion energy (40\&$\#$xa0;eV) to two different ion fluxes (low flux: 1022\&$\#$xa0;m-2\&$\#$xa0;s-1, high flux: 1024\&$\#$xa0;m-2\&$\#$xa0;s-1). The maximum of deuterium retention was observed at \~{}630\&$\#$xa0;K for low flux density and at \~{}870\&$\#$xa0;K for high flux density, as indicated from the thermal desorption spectroscopy data (TDS). Scanning electron microscopy observations revealed the presence of blisters with a diameter of up to 1\&$\#$xa0;μm which were formed at high flux density and high temperature (1170\&$\#$xa0;K) contrasting with previously reported surface modification results at such exposure conditions.},
