The results of helium implantation during sputtering of stainless steel are described in this paper. These experiments simulate the simultaneous bombardment of unconfined 3.5 MeV alpha particles and erosion due to sputtering primarily from the charge exchange neutral (D, T) flux. The results indicate that helium induced blister formation can take place, with simultaneous sputtering, under conditions appropriate to a fusion reactor. The critical experimental parameters of helium flux and surface velocity are in excellent agreement with simple calculations that predict the conditions under which helium induced surface deformation takes place.
