Plasma-Material-Wechselwirkung

What it is about

You will learn the physical and technical foundations of the interaction between plasma and material surfaces. After completing the module you will be able to describe the processes that lead to erosion and modification of plasma-impacted materials, and assess which investigation method is suitable for specific questions. You will also understand the influence of wall materials on the plasma in fusion devices.

What you will be able to do

• Describe erosion and surface modification by plasma qualitatively and quantitatively
• Name and classify different erosion processes (physical sputtering, chemical erosion, radiation-induced sublimation, arcs)
• Assess methods of surface characterization and their application
• Understand the effects of the plasma sheath and wall materials on plasma behavior in fusion devices
• Apply knowledge of vacuum technology, coating processes, and hydrogen retention

What the module consists of

• VorlesungDelivery of content and fundamentals; all slides and the lecture script are provided online
• Exkursion/LaboreinsichtVisit to accelerator, ion beam test stand and laboratories at the MPI for Plasma Physics to illustrate experimental investigations

Teaching method

• VortragPresentation of the technical content and concepts
• Online-Materialien (Folien, Skript)Support for self-study and as a reference work
