Phase and amplitude noises in the Tevatron RF system and the intrabeam scattering (IBS) produce longitudinal emittance growth with consecutive particle loss from the RF buckets. That causes a decrease of the luminosity and an increase of the background in particle detectors during the store. The report presents experimental measurements of RF system noise and the effect on the longitudinal emittance growth. There is a satisfactory agreement between measured noise spectral densities and observed emittance growth. For high bunch intensities, IBS plays an important role and has been taken into account. The sources of noises and plans for further system improvements are discussed.
