  • LHCb Hybrid to PedestalJohn Carroll

  • Metrology

  • Top of Silicon

    This side is Paddle and R sideR to Phi face to faceWidth 2.017mmR to Phi face to faceWidth 1.995mmTilt on left sideFrom CL 0.367mmTilt on right sideFrom CL 0.443mm

  • Hybrid

  • Tilt of HybridLeft side leans 221m Right side leans 216 m

  • ?

  • Detector Plane

    -53m0m-10m+172m

  • Top of Paddle

  • Position of Face

    Nominal distance from CL to face 0.56mmDistance on existing Pedestal 0.44mm

  • Summary1)Hybrid leans ~220 m (away from paddle)2) Paddle face offset in Z by 120 m3) Existing twist in hybrid (for hybrid #45 70 m)4)Accuracy of video measurement using focus 10 m
