Description
The High Luminosity Large Hadron Collider (HL-LHC) is entering its final development phase, requiring the optimisation of its vacuum layout to ensure reliable operation. The main upgrades with respect to the current LHC involve the Long Straight Sections next to the two large, general-purpose experiments (ATLAS and CMS), including new final focusing magnets and a full crab crossing implementation using superconducting crab cavities. Since residual gas critically affects collider performance, extensive vacuum simulations have been conducted to evaluate and minimise pressure levels. These include steady-state studies accounting for phenomena like photon, electron and ion-induced desorption, to determine pressure. The simulations employ several complementary tools: Molflow+ for Monte Carlo particle tracking in ultra-high vacuum conditions, Synrad+ for synchrotron radiation effects, and the MATLAB-based VASCO code for pressure stability analysis.
