Fusion research at ORNL encompasses many varied activities:
Plasma Material Interactions
The interaction between (fusion grade) plasma and the material surface at the edge of machines defines the boundary conditions of the device. These interactions serve to define both the parameters of edge plasma (and the device performance towards achieving fusion) and the longevity of the material surface (e.g. due to erosion and power handling limitations).
This is being studied experimentally in the Physics Integration eXperiment (PhIX).
Simulation and Modeling of PMI through the use of edge-neutrals codes, e.g. SOL-PS.
Collaboration at Plasma Experiments
Researchers participate in ongoing (and developing) plasma experiments worldwide through collaborations which aim to uncover fundamental physics of fusion grade devices.
