摘要:

Using the technique first described by Robinson and Rusbridge [Plasma Phys.11, 73 (1969)] electron temperature fluctuations have been measured in the scrape‐off layer of the TEXT tokamak [Nucl. Technol. Fusion1, 479 (1981)] to beT˜e/Te&bartil;0.4n˜e/ne. Particle and energy transport were estimated from ⟨n˜e E˜&thgr;⟩ and ⟨T˜e E˜&thgr;⟩ correlations. The fluctuation‐driven particle transport was consistent with earlier measurements and with measurements of global particle confinement. A high correlation of temperature and electric field fluctuations and a low but positive correlation between density and temperature fluctuations were observed.
