Particle Transport

    The plasma-surface interface composes one of the most interesting and important fields of study in plasma physics, and in the application of plasma physics to magnetic confinement fusion research. Both the plasma and the material surface simultaneously change characteristics due to their interaction, and affect each other in a complex, nonlinear manner. This dynamic interaction leads to several effects, such as net erosion of plasma-facing surfaces, tritium retention in deposit layers and plasma impurity contamination, which are all estimated to limit the viability of long-pulse plasma fusion devices. However, in general, these phenomena remain relatively poorly understood, primarily due to the lack of proper plasma-surface diagnosis.
