High erosion and re-deposition rates of tungsten in the highly collisional plasmas of Magnum-PSI

High erosion and re-deposition rates of tungsten in the highly collisional plasmas of Magnum-PSI

Prompt re-deposition strongly reduces the migration of eroded material in current fusion devices, thus lowering core dilution and extending the lifetime of the plasma-facing components. However, under the high-density ( $n_{\mathrm{e}} \gt 2 \times 10^{20}$ m ^−3 ), low-temperature ( $T_{\mathrm{e}}...
