Abstract
Electron temperature fluctuations are measured in the core of a tokamak plasma across the poloidal cross section. There is a strong poloidal asymmetry; the fluctuation amplitude peaks off the equatorial plane in four “lobes” symmetric about the equatorial plane on both the high- and low-field sides. At the plasma top the fluctuation amplitude decreases by over 2 orders of magnitude from its peak value. On the high-field-side equatorial plane the fluctuations also show a sharp reduction in amplitude.Keywords
