Introduction To Plasma Material Interactions

Plasma Material Interactions Dutch Institute For Fundamental Energy Plasma material interactions (pmi) refer to the complex processes and effects that occur when high energy plasma interacts with surrounding materials, particularly the plasma facing components (pfcs), which can lead to significant changes in material properties and limit their service lifetime. •this talk focuses on plasma material interactions (pmi) for fusion applications. •other areas where pmi is important: •semiconductor manufacturing. •electric propulsion . •solar wind space weathering of asteroids . •in this talk: “hydrogen” is short for “hydrogen isotopes” = h d t.

Understanding Plasma Surface Interactions For Enhanced Results Plasma material interactions (pmis) are a crucial aspect of various fields, including fusion energy, plasma processing, and space exploration. understanding the complex interactions between plasmas and materials is essential for advancing these fields and developing new technologies. However, tokamak experiments provide the data on plasma material interactions for the “real” tokamak plasma environment, which is often characterized by violent anomalous transport phenomena in multi species plasma and a long range migration of the eroded material. Such processes play an important role where the boundary plasma impacts on solid surfaces. elementary plasma surface interaction processes are investigated predominantly in dedicated laboratory experiments and compared to results from real surfaces from fusion devices. In this chapter, we examine in detail the interactions of these energetic particles and material surfaces to understand the basic mechanisms that drive plasma material interactions.

In this chapter, we discuss the basic interactions of plasma generated ions and charge neutral species with solid and liquid surfaces. As a result of the finite confinement of the core plasma, plasma particle and energy leaks outside of the core plasma region and interact with plasma facing components. Interaction of powerful plasma and particle beams (power densities up to hundreds of gw m −2 and time duration up to tens of ms) with various materials significantly damages exposed target surfaces and nearby components. • analysis of plasma conditions from metal tile campaign and planning of future diii d experiments and diagnostic implementation. • design and implementation of new heat flux diagnostics and ion energy distribution measurements.
