We reply to the comment by Li et al (submitted to Nucl. Fusion with this response) on our recent paper Nishijima et al (2023 Nucl. Fusion 63 126003). In this response, we address the existence of an incident ion energy, E _i , threshold for the deute

The annealing of ∼1 μm thick tungsten–deuterium co-deposit layers produced at 320 ± 25 K is found to induce changes in the desorptive release behavior and crystal structure. The changes in co-deposits were revealed by annealing in the temperatu

Properties of deuterium (D) supersaturated surface layers (DSSLs) formed in tungsten (W), such as thickness, internal microstructures, and D retention, are experimentally investigated as a function of the incident ion energy, E _i . W samples were ex

Beryllium co-deposit thermal desorption studies are reported that focus on the effect of D2pressure during layer formation, as pressure has been linked in prior work to the formation of a high-retention-capacity sharp-release-feature. A pressure rang

The release of deuterium from sputter magnetron produced tungsten co-deposit layers is studied by thermal desorption mass spectrometry and modelled with the diffusion reaction codes TESSIM and FACE. Layers up to ∼ 2 µm thick, produced at substrate

Deuterium retention was for the first time measured in tungsten samples simultaneously irradiated by W ions and exposed to D atoms at five different temperatures from 450K to 1000K. In order to obtain information on the defect concentration, samples

The growth of dendritic grains during solidification is often modelled using the Grain Envelope Model (GEM), in which the envelope of the dendrite is an interface tracked by the Phase Field Interface Capturing (PFIC) method. In the PFIC method, an ph
