HEAT simulation and IR data comparison for ST40 plasma-facing components
Nuclear Materials and EnergyThe Heat Flux Engineering Analysis Toolkit (HEAT) (Looby et al., 2022) was used to simulate the heat flux, qtarget, on ST40 molybdenum divertors. Results were compared with experimental infrared (IR) data.

Dust remobilization from rough planar surfaces in tokamak steady-state plasmas
Nuclear Materials and Energy, 2018 The ability of tungsten (W) dust to be remobilized from rough tokamak plasma-facing surfaces is investigated in this study. Atomic Force Microscopy is used to evaluate the adhesion force distribution between W spheroids of ∼1−10 µm radius and a rough W ...

Important problems of future thermonuclear reactors*
Nukleonika, 2015 This paper concerns important and difficult problems connected with a design and construction of thermonuclear reactors, which have to use nuclear fusion reactions of heavy isotopes of hydrogen, i.e., deuterium (D) and tritium (T).
