Simultaneous irradiation and thermal effects on 16 MeV proton irradiated tungsten samples
Simultaneous irradiation and thermal effects on 16 MeV proton irradiated tungsten samples
16 MeV protons have been used to irradiate 300 μm thick macroscopic W samples in a pilot experiment to 0.006 dpa damage dose under low and high temperature scenarios of ∼373 K and ∼1223 K, respectively. The linear pre-Bragg region has been used for damage where the electronic loss (heat) in the samp...

16 MeV protons have been used to irradiate 300 μm thick macroscopic W samples in a pilot experiment to 0.006 dpa damage dose under low and high temperature scenarios of ∼373 K and ∼1223 K, respectively. The linear pre-Bragg region has been used for damage where the electronic loss (heat) in the sample amounts to 1.5 MW · m−2. Post high-temperature irradiation, the W sample has been recrystallized as seen under the scanning electron microscope. Indentation measurements on the surface show a softening of 0.6 GPa post-recrystallization against an irradiation hardening of 0.8 GPa for the low-temperature irradiation scenario. |
