| Title | 335: Off-axis NBCD measurement in steady state scenario | ||
| Name: | Jin Myung Park parkjm@fusion.gat.com | Affiliation: | Oak Ridge National Lab |
| Research Area: | Steady State Heating and Current Drive | Presentation time: | Not requested |
| Co-Author(s): | Measure off-axis NBCD profiles in high beta steady-state scenario. | ITPA Joint Experiment : | No |
| Description: | Measure local NBCD profiles at betaN ~ 2.8 with qmin ~ 1.0 and ~ 2.0 by comparing two discharges with and without OANB. Focus will be placed on obtaining stationary discharges at high beta as long as possible for accurate differential current drive analysis. (1) low qmin without OANB: Restore 147379 with the following changes: i) 30L & 30R in timcon, 330L & 330R in PCS betaN feedback, ii) take out 150LR completely, iii) apply 210RT at 70 kV, 10 on, 90 off starting after H-mode achieved (2) low qmin with OANB: Reproduce (1) with the following changes: i) put 150L & 150R in PCS control and prioritize over 330's. (3) high qmin (~2) without OANB: Restore 147394 with the same changes in (1) (4) high qmin (~2) with OANB: Reproduce (3) with the following changes: i) put 150L & 150R in PCS control and prioritize over 330's. This 4-point scan will also provide data set to investigate transport characteristics of high qmin discharges in great detail. |
