Strong correlation was observed between the air temperature fluctuation and the fluctuations of the beam size and beam position. It was found that different temperature sources were responsible for the fluctuations of the beam position in different directions (vertical and horizontal). The sensitivity factors of the fluctuations of the beam performance to the temperature fluctuation were measured. PB - JACoW Publishing CP - Geneva, Switzerland ER -
