    “…Later, the periodic “ring dispersion” was reconstructed from the full first-turn trajectory of an injected off-momentum beam, by removing, at each location, the large incoming dispersion mismatch, forward-propagated via the optics model. Various combinations of inverted trim quadrupoles were considered in this model until reaching a good agreement of reconstructed dispersion and prediction.…”

    “…Optics studies based on the V6.503 nominal optics have been performed, aiming at improving the collimation efficiency by adjusting the phase advance from IP1 to IP5 to be π/2 off a multiple of 2π such that the off-momentum beta-beating is localized to the left side of the LHC ring. …”

    “…While one of the initial goal was to squeeze the optics down to a B* of 25 cm, optics solutions with a B* of 30 cm are already at the edge of feasibility, both in terms of the IT and MS mechanical acceptance, gradients of the MS and DS quadrupole magnets, and correctability by the arc sextupoles of the huge chromatic aberrations generated at low B*. …”

    “…These limitations will be analyzed in detail, in particular concerning the chromatic correction of the new inner triplet which requires a global modification of the present LHC optics. Concerning the high luminosity insertions, the layout of the new IT and the corresponding injection and collision optics (with Beta* ≥ 30 cm) will be present ed and studied in detail both in terms of mechanical aperture, chromatic correction, squeeze-ability, dynamic aperture and beam-beam effects…”
