Description
The High Energy Large Hadron Collider (HE-LHC), a possible successor of the High Luminosity LHC (HL-LHC) aims at reaching a centre-of-mass energy of about 27 TeV using basically the same 16 T dipoles as for the hadron-hadron Future Circular Collider FCC-hh.
Before concluding on two possible baseline desings, namely an 18$\times$90 (18 LHC-like arc FODO cells with 90$^{\circ}$ phase advance in both transverse planes) and a 23$\times$90 lattice, various arc FODO cell and dispersion suppressor (DS) options have been generated, using ALGEA (Automatic Lattice GEneration Application), and tested. Minimizing the geometry offset results in updated arc and DS designs, and leads to sufficient optics integration of interaction regions, specially designed for the HE-LHC. Merits of each design are highlighted and possible solutions to overcome beam stay clear minima are presented.
