This work analyzes the first measurements of the electron temperature fluctuations (δTe) from the recent 2022 experimental campaign where an extended plasma current of 800 kA is achieved. The δTe levels are measured with a correlation ECE diagnostic and compared for different ▽Te in favorable and unfavorable drift configurations.
