| Title | 257: Poloidal rotation as a function of toroidal rotation | ||

| Research Area: | Rotation Physics | Presentation time: | Not requested | Co-Author(s): | K.H. Burrell |
| Description: | Recent theoretical work by S.K. Wong suggests that signficant corrections over standard neoclassical theory are required at large toroidal rotation. Hence we would like to establish whether the discrepancy between the measured and neoclassical poloidal rotation (from NCLASS) scales with the toroidal rotation. | ||
| Experimental Approach/Plan: | A plasma where the anomalous poloidal rotation has previously been observed should be used as a reference (probably a QH-mode plasma). The poloidal rotation should be measured during a systematic scan of the toroidal rotation. Some data probably exists on this already, however, if QH-mode can be pushed further to balanced or co-direction as is planned, then this would provide a better data set. | ||
| Background: | Poloidal rotation discrepancies between measurement and NCLASS have been observed, but typically exists in rapidly rotating (toroidally) plasmas. | ||
