  1. Key features of the upgrade optics and layout possibly impacting on collimation R. De Maria

  2. Outlook • New element comparisons: length, aperture, position, aperture separations. • Beta functions, dispersion and aperture margins: • Triplet Area • TAN D2 Q4 Area • Q8-10 in the squeeze • Arcs in the squeeze

  3. Triplet layout Nominal layout: NbTi: (3 cryostats) • HLHC V.10 layout: • Nb3Sn • 6 cryostats

  4. Crab cavity layout • Nominal layout: • one cryostat for D2 Q4 and corrector package HLLHC V1.0 layout • Separate D2 and Q4 cryostat; • Total cavity voltage for 590murad 12MV (for full crabbing); • 3 cavities allocated per side per beam; • Alternated location for voltage equalization; • Introduce stronger corrector for crossing scheme gymnastic.

  5. New elements: single bore

  6. New elements: 2-in-1

  7. Mechanical tolerances • V6.5 measured values • HL-LHCV1 (ground motion + fiducialisation) in mm: • Triplet (0.6,0,0)+(0,1,1) • D1/D2 (0.84,0.36,0)+(0,1,1) • Q4/Q5 (0.84,0.36,0)+(0,0.9,0,6)
