Streit's paper "Temperature Threshold for Preferential Bubble Formation on Grain Boundaries in Tungsten Under in-situ Helium Irradiation" published in Scripta Materialia.
April 2020
In this paper, in-situ irradiation/transmission electron microscopy (TEM) is employed to study the effects  of low energy (16 keV) helium implantation effects on tungsten (a plasma facing material and divertor candidate for fusion power due to its attractive physical properties) at two elevated temperatures of 1073 and 1223 K.
