comments:

  • 12 bunches

  • dip of lifetime at start of ramp

  • drop of lifetime to 5 h at start of collisions

  • emittance from emittance scans at H 1.8 um and V 1.6 um

  • phase cogging to move spot in the IPs along z position

  • lumi optimizations in all beta*

  • cross section for PU calculation was set to ppref value so leveling was more aggressive

  • around 60 cm, impact on effective cross section and changes in bunch length

  • xing leveling was made more aggressive to speed up the fill and test the machinery, down to 120. leveling was too aggressive and pileup was higher than what was supposed to
