摘要：
The Belle II experiment is a substantial upgrade of the Belle detector and will operate at the SuperKEKBenergy-asymmetric e+e- collider. The accelerator has already successfully completed the first phase of commissioning in 2016. The first electron versus positron collisions in Belle II were delivered in April 2018. The design luminosity of SuperKEKB is 8 x1035 cm(-2)s(-1), and the Belle II experiment aims to record 50 ab(-1) of data, a factor of 50 more than the Belle experiment. This large dataset will be accumulated with low backgrounds and high trigger efficiencies in a clean e+e- environment. This contribution will review the detector upgrade, the achieved detector performance and the plans for the commissioning of Belle II.
