| Abstract |
The next generation of B-Factory, the SuperKEKB electron-positron collider at KEK (Japan) has started after two years shutdown from the Phase 1 commissioning in 2016. The first phase for the vacuum scrubbing in 2016 and the second phase focused on the verification of the novel "nano-beam" collision scheme were successfully completed in 2018. The modifications between Phase 1 and Phase 2 follows Phase 3 are installations of the final focus system and the Belle II detector. In order to accomplish the higher luminosity more than the predecessor KEKB , the nano-beam scheme is studied with higher bunch currents to reduce the beam-beam blowup which degrade the luminosity. The new collision scheme is reviewed and the luminosity performance and overall status in the Phase 2 and Phase 3 commissioning are presented.
