| Title | 319: Stochastic thermal transport in DND | ||
| Name: | Michael J. Schaffer ( |
Affiliation: | General Atomics |
| Research Area: | Thermal Transport in the Plasma Boundary | Presentation time: | Not requested | Co-Author(s): | Ilon Joseph, Petrie, Lasnier, others TBD |
| Description: | Apply a RMP field to a double-null diverted (DND) plasma. Measure footprint splitting in both upper and lower divertors and compare offline with computed footprints. Can the target powers be balanced between the two divertors? | ||
| Experimental Approach/Plan: | If my idea #315 for an L-mode test plasma for stochastic thermal transport experiments is successful, the present experiment should be tried with both H- and L-mode DND plasmas. | ||
| Background: | Most observations of split divertor footprints in DIII-D have been with single null diverted plasmas. For double nulls, one expects an stochastic edge to couple to spiral footprints in both outer divertors, but much weaker footprint splitting in the inner divertors. | ||
| Resource Requirements: | -- | ||
| Diagnostic Requirements: | Must have IRTV data from both upper and lower divertors. | ||
| Analysis Requirements: | Trip3d | ||
| Other Requirements: | -- | ||
