HLLHCV1.0: HL-LHC Layout and Optics Models for 150 MM Nb$_{3}$Sn Triplets and Local Crab-Cavities

\nThe paper presents the latest layout and optics models for the HL-LHC upgrade project. As an evolution from the previous version SLHCV3.1b, it integrates the new Nb$_{3}$Sn triplet (140 T/m, 150 mm) with all the additional magnets needed to be compatible with a β* reach of 15 cm and beyond. The collision optics implements the ATS [1] scheme which is able to provide very low value of β* and at the same time warrants outstanding control of the chromatic aberrations within the strength limits of the existing arc sextupole scheme of the LHC. The optics models include the injection and collision optics for proton and ion operations foreseen for the HL-LHC, with improved squeezeability of the existing IR2 and IR8 insertions. An aperture model and a series of optics matched in thin lenses complete the needs for a large range of dedicated beam dynamic studies (dynamic aperture, beam-beam effects, collimation).
