SuperKEKB achieved a peak luminosity of 5.1x10^34/cm^2/s in December 2024. The next milestone is 1x10^35/cm^2/s. However, one of the major limitations on achievable luminosity is the maximum accumulated current, which is determined by the balance between beam injection and beam lifetime. Beam injection involves many factors. The most important improvements to increase the maximum accumulated current are listed below.
1) Investigation of the e- emittance growth in the beam transport line
2) HER synchrotron injection
3) Improve the dynamic aperture of HER by correcting QCS cancel coil error
4) Improve the LER injection beams and alignment of the injection region
