Sumario:Coupled-bunch instabilities due to electron cloud effect have been observed in KEKB LER. The effect was clearly explained by the electron cloud effect (ECE) in the drift space by the numerical simulations. For SuperKEKB collider which is the upgrade of the KEKB collider, several methods to mitigate the ECE have been applied. The effectiveness of those methods has been evaluated using the beam in Phase 1 and Phase 2 operation of SuperKEKB. Preliminary experimental results will be shown.
