Abstract :
Commissioning of KEKB started at the end of the last year. In the early stages of the commissioning, we observed transverse instabilities in both rings and started tuning of the bunch feedback systems. Even though the tuning is now at the initial stage, the feedback systems are contributing to an increase of the maximum storable currents in the KEKB rings. Feedback-related systems, tune meters and bunch-current monitors, are also working well
