  2. MDI - Survey mini galleries • Left side w.r.t right side • Requirements: • Determination of left reference line w.r.t right reference line : within ± 0.1 mm rms • Monitoring of left reference line w.r.t right reference line : within a few microns • Monitoring of the position of left QD0 / right QD0 within ± 5 μm rms Solutions: • Determination of left reference line w.r.t right reference line &monitoring of one BDS w.r.t other: link stretched wires on both side by a common reference (as in the LHC), using the survey galleries 2 MDI session at KILC12- Daegu, South Korea
