| Title | 221: Gas Injection Feedback with Radiation Measurements | ||
| Name: | Egemen Kolemen ekolemen@pppl.gov | Affiliation: | Princeton Plasma Physics Laboratory |
| Research Area: | Divertor & SOL Physics | Presentation time: | Requested |
| Co-Author(s): | T. Petrie, N. Eidietis, D. Humphreys | ITPA Joint Experiment : | No |
| Description: | Measure the radiation at various location in the plasma (main, divertor, ...) using bolometer channels. By using these real-time measurements, adjust the gas injection of various species (Argon, Neon, Deuterium,...) to keep power exhaust, detachment, and many other parameters at desired values. | ITER IO Urgent Research Task : | No |
| Experimental Approach/Plan: | Develop and test the radiation control.
Use it to control power ?ux into the divertor, divertor temperature and the power load as estimated by the bolometric calculations of main chamber and divertor radiation | ||
| Background: | This feedback has been successfully used at Asdex-Upgrade with great utility. (See, A. Kallenbach et al 2012 Nucl. Fusion 52 122003 and reference within) | ||
| Resource Requirements: | PCS code upgrade and 1/2-1 day of experimental time to study the physics. | ||
| Diagnostic Requirements: | -- | ||
| Analysis Requirements: | -- | ||
| Other Requirements: | -- | ||
