| Title | 397: New ORNL pellet dropper to modify edge instability drives | ||
| Name: | Terry L. Rhodes ( |
Affiliation: | University of California, Los Angeles |
| Research Area: | Transport | Presentation time: | Not requested | Co-Author(s): | Jernigan, Boedo, Moyer, McKee, Schmitz, Wang, Zeng |
| Description: | Use new pellet dropper to modify edge instability drives in both L and H mode. We will utilize this new capability to probe the edge instabilities by periodically modifying the edge n_e and Te while simultaneously measuring with all available turbulence and profile diagnostics. | ||
| Experimental Approach/Plan: | -- | ||
| Background: | Identification of edge fluctuations, drive, etc. (pedestal and SOL) is not complete. The edge is a complicated interconnected system and there is not yet a complete picture of the dynamics there. The pellet dropper may allow a way to probe this system by locally modifying the edge drives in a new manner. | ||
| Resource Requirements: | pellet dropper (new ORNL system) plus all relevent turbulence and profile diagnostics | ||
| Diagnostic Requirements: | -- | ||
| Analysis Requirements: | -- | ||
| Other Requirements: | -- | ||
