                      deuterium retention and blistering in tungsten has been
                      investigated after exposure to low-energy (40 eV) and high
                      flux (~1022 D m−2 s−1) deuterium plasma under high
                      fluence of 1  ×  1026 D m−2 with various surface
                      temperatures (450 K, 550 K and 750 K). The undamaged
                      and pre-damaged tungsten show a similar temperature
                      dependence of deuterium-induced blistering, as well as
                      deuterium retention in the near surface (within 300 nm).
                      Deuterium concentration in the near surface decreases with
                      increasing the surface temperature in deuterium plasma
                      exposure. For both cases, the most serious blistering is
                      present at the surface temperature of 550 K. Due to the
                      creation of pre-damage the size of surface blister becomes
                      much larger and the near-surface deuterium concentration
                      becomes higher. Analysis of blistering-related cavities in
                      the pre-damaged and undamaged tungsten indicates that in
                      pre-damaged tungsten deuterium aggregates in the place with
                      a much larger depth. Based on the comparison of the
                      pre-damage induced increment of deuterium retention within
                      the near surface region (damage layer) and in the bulk, it
                      reveals that the pre-damage enhances deuterium retention in
                      the bulk more strongly than that in the near-surface region,
                      suggesting that the deuterium flux diffusing into the bulk
                      of pre-damaged tungsten is largely improved.},
