Dust in magnetic fusion devices

TLDR

Dust in magnetic fusion devices has been studied recently, but current models of dust–plasma interactions have limitations and gaps remain in experimental and theoretical approaches. The study assesses dust’s role in current fusion devices and ITER and proposes future research directions. The authors discuss dust diagnostics, experimental findings, theoretical aspects, and compare theoretical estimates and numerical simulations with experimental data. The comparison of theoretical estimates and numerical simulations with experimental data reveals discrepancies that point to limitations in current dust–plasma interaction models.

Abstract

This paper reviews recent results of the study of dust in magnetic fusion devices. Assessment of the role of dust in current fusion devices and ITER is presented. Dust diagnostics, main experimental results, different theoretical aspects of dust in fusion plasmas, as well as the comparison of theoretical estimates and numerical simulations with available experimental data are discussed. Some limitations of current theoretical models of dust–plasma interactions and the gaps in current experimental and theoretical approaches to dust study in fusion devices are considered. Possible directions for further advancements are suggested.
