Abstract	We describe the main general changes as relevant for the experiments, and in particular the changes in the machine-detector interface (MDI) region extending from the merging of the LHC beampipes into a single experimental chamber before the inner triplet to the start of the experimental beampipe in the experimental cavern. The geometry of this region is optimized to provide a maximum decoupling of the activities in the tunnel and inside the experimental caverns. Massive absorbers are used to strongly reduce the flux of secondary particles produced in collisions in the interaction region into the tunnel, and at the same time help to protect the experiments from beam induced losses and backgrounds. This chapter explains the main challenges within that region and how they will be solved to cope with the new requirements coming from the luminosity upgrade.
