Tungsten is the candidate divertor target material in future fusion reactors. The tungsten expected to serve a severe environment of high temperature and high-energy neutron irradiation. This can lead irradiation-induced recrystallization tungsten, thereby increasing possibility intergranular brittle failure compromising safe operation divertor. Thus, clarifying mechanism crucial. However, curr...

In the field of radiation effects in materials, a detailed and precise description of the radiation environment used to damage samples is often required to make sense of subsequent materials analysis. The types of reactions and extent of damage that occur during irradiation strongly depend on the flux spectrum of the particular facility. Different neutron activation techniques for characterizin...

This paper demonstrates the feasibility of creating specific defects in double-heterostructure InGaN/GaN commercial light-emitting diodes by neutron irradiation. Using controlled neutron energy, only one failure mechanism can be activated. Defects are located on the side of the chip and increase the leakage current driven by the well-known Poole–Frenkel effect with Ec − ET = 130 meV electron tr...
