Tritium (T) trapping in tungsten after plasma exposure (deuterium (D), helium (He), nitrogen (N), argon (Ar)) was studied using an imaging plate technique. Specimens were exposed to D and T mixed gas at 77 and 573 K to distinguish T trapped at the outermost surface and several tens of nanometers, respectively. He followed by N, Ar and D plasma exposures resulted in the largest increase in T trapping. This was interpreted to result from He bubble layers that can increase the surface area by formation of pores connected to the surface and/or an increase in surface trapping sites. T exposure at 77 K was found to be a very useful method to observe plasma-induced changes to T trapping at the outermost surface. © 2014 The Royal Swedish Academy of Sciences.
