| Title | 396: ELM interaction with main chamber wall | ||
| Name: | Dmitry Rudakov ( |
Affiliation: | University of California, San Diego |
| Research Area: | Boundary | Presentation time: | Not requested | Co-Author(s): | J. Yu, J. Boedo, N. Brooks, M. Groth, T. Evans, M. Fenstermacher, E. Hollmann, C. Lasnier, A. Leonard, R. Moyer, P. Stangeby, J. Watkins, P. West, C. Wong |
| Description: | Characterize ELM interactions with the main chamber wall under varying density/collisionality. Measure material erosion rates at the outer wall using MiMES. | ||
| Experimental Approach/Plan: | Synchronize as many fast edge/pedestal as possible to get reliable relative timing measurements. Perform measurements of the radial and poloidal propagation of ELM pulses at 3-4 different normalized densities n/n_GW of 0.4-0.9. Perform material sample exposure with MiMES. Turn on I-coil during the last second of the shot to attempt ELM reduction. | ||
| Background: | |||
| Resource Requirements: | 1 day experiment; LSN H-mode, 4 sources of NBI, I-coils | ||
| Diagnostic Requirements: | All available fast edge and pedestal diagnostics; profile diagnostics | ||
| Analysis Requirements: | -- | ||
| Other Requirements: | -- | ||
