| Description: | |||
| Experimental Approach/Plan: | 1) Reproduce the small, upward-shifted plasmas (83300.03000) with the existing (horizontal) NBI. -2.1T/ 0.6 MA, ~10 MW. Bring the plasma back to mid-plane quickly (within 50-ms) to assure the MSE measurements.
2) Repeat the experiment with an opposite BT direction (this can be done in other Working Group) 3) Change the plasma conditions: reduce BT to 1.6 T (q95~5); Increase nebar to 6x10^19 | ||
| Background: | |||
| Resource Requirements: | Machine Time: 2 days, one day with positive (reverse) BT direction and the second day with negative (normal) BT direction (one day can be done in Advance Scenario Development area)
Number of gyrotrons: 4 desirable Number of neutral beam sources: 7 | ||
| Diagnostic Requirements: | FIDA (UC, Irvine), MSE with counter-system (LLNL) | ||
| Analysis Requirements: | Scenario modeling with TRANSP, NUBEAM/GLF23/ONETWO | ||
| Other Requirements: | No | ||
