| Title | 487: Target plate conditions during ELM suppression | ||
| Name: | Jonathan G. Watkins ( |
Affiliation: | Sandia National Laboratories |
| Research Area: | ELM Control & Pedestal Physics | Presentation time: | Not requested | Co-Author(s): | Evans, Moyer, Lasnier, West, Schaffer |
| Description: | Look for target plate structures and plasma conditions during ELM suppression. Monitor evolution of structures with edge q and I-coil current. Verify heat flux with thermocouples and Langmuir probes. | ||
| Experimental Approach/Plan: | Position strike point on top of tc array and monitor temp rise during shot to get heat flux. Move strike point to get better profile with LP (and TC?). With the improved TC and Langmuir probe array we hope to produce better profiles and show the evolution of conditions during parameter scans (q95, density, Icoil current, rotation, ...) | ||
| Background: | Evidence of structures has been observed with the floor probes - especially in the floating potential. The heat flux measured has been lower than expected. With the new TC array, we hope to verify the IRTV and extend the measurement into the view-blocked baffle region. | ||
