The target luminosity for SuperKEKB is 8×1035 cm−2s−1, this is 40 times larger than the luminosity at KEKB. The improvement is mostly due to a so-called 'nano-beam' scheme, originally proposed[7] for the cancelled[8] SuperB experiment. In the nano-beam scheme at SuperKEKB, the beams are squeezed in the vertical direction and the crossing angle is increased, which reduces the area of the crossing.[3] The luminosity is further increased by a factor of two, due to a higher beam current than KEKB.[1] The focus and crossing angle is achieved by two new superconducting quadrupole magnets at the interaction point[1] that were installed in February 2017.[9]
