30. Comments on RR Lattice result No inconsistency in the TBT data Beta waves in both planes –Horizontal plane: ~35% in Δβ/β. –Vertical plane:~25% –Matched by R90 to ~5% level. Compare TBT orbit with R90 calculation –Initial positions & angles fitted by TBT analysis. –Good match with matched base lattice. –Not perfect As judged by BPM resolution. Calibration factors –Measured beta functions are credible. Injection test with IPM. December 17, 2014
