Operational experience and commissioning of the Belle II vertex detector

The construction of the new accelerator at the Super Flavor Factory in Tsukuba, Japan, has been finalized and the commissioning of its detector (Belle II) has started. This new e+e machine (SuperKEKB) will deliver an instantaneous luminosity of 8 1035 cm2s1, which is 40 times higher than the world r...
