Description
SuperKEKB, the upgraded successor to KEKB, is an asymmetric electron-positron collider. Aiming for 40 times higher luminosity than KEKB by shrinking the beams to "nano-beam" size at the interaction point while doubling the beam currents, SuperKEKB has been commissioned in a phased manner. In the Phase 2 operation of SuperKEKB, the first collisions were recorded and the smallest value in the world of the vertical beta function at an interaction point was achieved. Phase 3 starts in March 2019, and the first physics run also starts with a fully equipped Belle II detector. The recent progress and performance of the SuperKEKB accelerator are reported on here.
