CMS-PRF-21-001
Schematic layout of the beam line between the interaction point and the RP locations in LHC sector 56, corresponding to the negative z direction in the CMS coordinate system. The accelerator magnets are indicated in gray; the collimator system elements in green. The RP units marked in red are those used by PPS during Run 2; the dark gray ones are part of the TOTEM experiment. In Run 3 the ``220 near'' horizontal unit is used in place of the ``210 near''.
