HER LER Specific Luminosity Bucket Dependence

Luminous Region – Z axis

Luminous Region – “X axis” Resolution subtracted (36 um)

Luminous Region – “Y axis” Resolution dominated

Luminous Region Residual Tilts

Boost Trajectory Residual Means

Boost Trajectory Spreads

Specific luminosity depends upon bucket in the minitrain –Not understood, not solved Luminous z position varies along minitrain –Known RF loading Luminous x-size increases along minitrain by ~ +2 um / 25 bunches –Not large enough to explain lumi drop Boost y-prime varies along minitrain by ~ -20 urad / 25 bunches –Quite small; maybe a detector/systematic effect?
