Exploring a Novel Way to Mitigate Surface Damage in Tokamaks

Executive Summary

We will model the effects of electron emission from surfaces in tokamaks, a type of magnetic fusion energy device, using simulation codes and validation experiments to determine whether these emissions can reduce material damage to tokamaks. This research supports national energy security by helping us overcome a principal challenge in achieving practical fusion energy.
