The target luminosity is 8x10³⁵ cm⁻²s⁻¹, which is 40 times higher than that achieved at KEKB. Construction of SuperKEKB is progressing on schedule, and beam commissioning is scheduled in 2015. Fabrication, treatment and installation of vacuum components, magnets and power supplies, and beam diagnostic and feedback systems are ongoing. Improvement of RF system and strengthening of cooling system for magnets and beam pipes are also underway. Detailed design of the interaction region has been finalized, and final focus superconducting magnets are under production. The damping ring tunnel and buildings has been completed, and installation of the accelerator components started. The upgrade of the injector linac is also progressing. This paper describes construction status of SuperKEKB main rings and the damping ring as well as recent design progress.
