SuperKEKB machine and Belle II detector status

The KEK Super B factory consists of the asymmetric energy e + e − collider SuperKEKB, operating at the energy of the ϒ ( 4 S ) resonance, and the Belle II detector, which will watch the products of the electron-positron collisons. This facility will be built by upgrading the present KEK B factory to allow both to minimize the construction costs and to resume data taking in the year 2014. The main goal of the new facility is to achieve an instantaneous luminosity of 8 × 10 35 cm − 2 s − 1 , leading to a data set of about 50 ab −1 around the year 2022. In this article, we briefly review the technical design of the SuperKEKB collider and the Belle II detector.
