W samples were exposed to steady state and pulsed He plasmas at surface base temperatures from 670 to 1170 K. The same exposures were repeated in hydrogen (H) to allow a direct comparison of the role of the ion species on the thermal shock resistance. Exposure to He plasma pulses caused the formation of fine cracking network on W samples which occurred at a higher density and smaller depths compared to H pulsed plasma irradiation. The peak temperature reached during an ELM-like plasma pulse increased by a factor ~1.45 over the 100 s of He plasma exposure, indicating a deterioration of the thermal properties. Transient loading experiments were also performed using a high power pulsed laser during He plasma exposure, showing a significant modification of the target thermal response caused by the surface damage. The effect of He-induced morphology changes on the thermal response modification was found to be very small compared to that of transient-induced damage. 000837211 536__ $$0G:(DE-HGF)POF3-174$$a174 - Plasma-Wall-Interaction (POF3-174)$$cPOF3-174$$fPOF III$$x0 000837211 588__ $$aDataset connected to CrossRef 000837211 7001_ $$0P:(DE-HGF)0$$aDe Temmerman, Gregory$$b1 000837211 7001_ $$0P:(DE-HGF)0$$aHuisman, Arnout E$$b2 000837211 7001_ $$0P:(DE-HGF)0$$aBardin, Sebastien$$b3 000837211 7001_ $$00000-0002-5066-015X$$aMorgan, T.
