| Title | 325: Document turbulence change with rotation in AI, and compare with theory | ||
| Name: | Wayne Solomon solomon@fusion.gat.com | Affiliation: | General Atomics |
| Research Area: | Turbulence & Transport | Presentation time: | Not requested |
| Co-Author(s): | GR McKee | ITPA Joint Experiment : | No |
| Description: | (Duplicate of #324) The aim of this experiment is to document changes in turbulence levels associated with controlled changes in the rotation and q profiles, for benchmarking and validation against transport codes including GYRO and TGLF. | ITER IO Urgent Research Task : | No |
| Experimental Approach/Plan: | Repeat discharges based on torque ramp down shots, and halt the ramp down at different rotation levels. Avoid ECH for mode control until necessary (lowest rotation levels). Repeat for different q95 and q-shear. | ||
| Background: | A significant reduction in confinement has been observed for AI discharges at low rotation, and while changes in turbulence resulting from the reduced ExB shear has been implicated, this has never been directly confirmed. | ||
| Resource Requirements: | 1 day expt, 6 gyrotorons with NTM control, 210 beams | ||
| Diagnostic Requirements: | BES, FIR, DBS and all fluctuation diagnostics | ||
| Analysis Requirements: | |||
| Other Requirements: | |||
