Final Technical Report: Development of long-pulse heating and current drive actuators and operational techniques compatible with a high-Z divertor and first wall
- College of William and Mary, Williamsburg, VA (United States)
During the 4 years of funding we made significant progress on how heat flux width scales with changes in drifts and transport using SOLPS-ITER. We were able to show that while the 0D heuristic drift model is a good fit in certain scenarios, it does not capture the physics fully and changes in radial transport need to be incorporated when this model is expanded to 2D. We were able to show through SOLPS5.0 simulations that while neutral fueling plays a dominant role in setting the SOL density profile, an inward pinch needs to be included when we compare the time-dependent changes from the simulations with experiments on JET.
