Commissioning of the Phase-I SuperKEKB B-Factory and Update on the Overall Status

The SuperKEKB B-Factoryat KEK (Japan), after few years of shutdownfor the construction and renovation, has finallycome to the Phase-1 commissioning of the LER and HER rings, without the finalfocus system and the Belle II detector. Vacuum scrubbing, optics tuning and beam related background measurements were performed in this phase. Low emittance tuning techniques have also been applied in order to set up the rings for Phase-2 with colliding beams next year. An update of the finalfocus system construction, as well as the status of the injection system with the new positron damping ring and high current/low emittance electron gunis also presented.
