Abstract
This paper presents the research results the surface structure evolution of high-purity tungsten after irradiation with 350 keV protons and subsequent annealing in the temperature range 600 – 1000 °C. Irradiation to a fluence of 5×1017 cm‒2 leads to blisters formation on the irradiated surface. Successive two-hour annealing results in the evolution of the distribution of blisters - the total number of blisters decreases while the fraction of larger blisters increases. At an annealing temperature of 1000C, the blisters dissolve. Do not observed the blisters disclosure and surface flaking both after proton irradiation and subsequent annealing in temperature range 600 – 1000 °C.
