Beam losses far downstream of the high luminosity interaction points of LHC - intermediate results

We report a study on beam losses in the insertions IR1 and IR5 of LHC. We considered proton-proton collisions with a relatively small momentum transfer which induce distant losses. We show that the level of these losses is high enough to quench the quadrupoles Q5 in the straight sections and probabl...

description We report a study on beam losses in the insertions IR1 and IR5 of LHC. We considered proton-proton collisions with a relatively small momentum transfer which induce distant losses. We show that the level of these losses is high enough to quench the quadrupoles Q5 in the straight sections and probably the dipoles B8 in the dispersion suppressors. We confirm that collimators upstream of Q5 can prevent those quenches. Beam loss distributions in the dispersion suppressors are computed in the presence of these collimators and associated radiological results are discussed. Associated cryogenic power load are quantified.
