| Title | 430: Measure rotation screening of known applied error fields | ||
| Name: | T. C. Luce ( |
Affiliation: | General Atomics |
| Research Area: | Error Fields | Presentation time: | Not requested | Co-Author(s): | -- |
| Description: | There is no consensus regarding the screening of error fields from penetrating a rotating plasma. This proposal focuses on trying to measure the penetration by observing the rotation response to an applied error field at different fixed applied torques. Related to 20, 46, and 374. | ||
| Experimental Approach/Plan: | Set up pure co-NBI plasma that is stationary and robust. Apply oscillating non-resonant and resonant error fields with sufficient amplitude to detect the velocity variation with CER measurements. Repeat with decreasing torque input and compare magnitude and radial profile of velocity response. Switch to counter Ip and repeat. | ||
