Luminosity performance of SuperKEKB

Accelerator Physics 2023-06-06 v1

Abstract

Since April 2020, the SuperKEKB has been operating with the crab waist scheme. The luminosity record achieved in June 2022 was 4.71×1034 cm2s14.71 \times 10^{34} \text{ cm}^{-2}\text{s}^{-1}, which overtook its predecessor KEKB by more than a factor of 2. The beam-beam interaction plays a key role in causing vertical blowup and consequently limiting the luminosity performance of SuperKEKB. In this paper, we examine luminosity tunings under the influence of beam-beam effects and review the luminosity performance of SuperKEKB with the crab-waist operation from 2020 to 2022.
