Accelerator based fusion reactor

Nuclear Fusion, 2017
A feasibility study of fusion reactors based on accelerators is carried out. We consider a novel scheme where a beam from the accelerator hits the target plasma on the resonance of the fusion reaction and establish characteristic criteria for a workable reactor. We consider the reactions $ d + t \rightarrow n + α, d + {}^3H_e \rightarrow p + α$, and $p

Intergranular blistering in tungsten: a survey of grain-boundary-freedom dependence using tungsten with inclined microstructure

Nuclear Fusion
The dependence of hydrogen-induced intergranular blistering on the grain boundary (GB) was investigated in chemical vapor deposition tungsten (CVD-W). Three specific inclined CVD-W samples were prepared by cutting across the surface at specific angles ...
