 note = {The effect of periodic irradiation on Deuterium (D) retention and blistering in Tungsten (W) was investigated. W samples were exposed to D plasma at a fixed fluence while varying the irradiation cycle number (1-shot, 2-shots and 3-shots). Exposure energy and flux were ∼50 eV and ∼1 × 1022 D m−2 s−1, respectively. Sample temperatures were 537 K and 643 K. At 573 K, D retention and blister density decreased with increasing number of irradiation cycle. In contrast at 643 K, D retention showed no dependence on number of irradiation cycle. Therefore, sample temperature during irradiation is an important parameter in comparing the results of continuous and periodic irradiation, especially in studies involving extremely-high-flux (>1024 D m−2 s−1) irradiation and fluence dependency of D retention.},
