Handling collision debris in quad- and dipole-first LHC IR options

Detailed MARS15 Monte Carlo energy deposition calculations are performed for two main designs of the LHC interaction regions (IR) capable to achieve a luminosity of 1035 cm-2 s-1: a traditional quadrupole-first scheme and the one with a dual-bore inner triplet with separation dipoles placed in front of the quadrupoles. It is shown that with the appropriate design of the Nb$_{3}$Sn magnets, IR layout and a number of protective measures implemented, both schemes are feasible for the LHC luminosity upgrade up to 1035 cm-2 s-1.
