Title: Upgrade of the CMS Outer Tracker

Abstract content With the foreseen upgrade of the LHC to the High-Luminosity LHC in the next decade an instantaneous luminosity of 5x10^34 cm^-2 s^-1 and an integrated luminosity of 3000 fb-1 are expected. This, together with the expected average pileup of 140 leads to high occupancy and high radiation levels and thus necessitates an upgrade of the CMS Tracker. In order to cope with these challenges imposed by the HL-LHC environment, the silicon strip granularity will be increased and the sensors will be cooled to -20^oC. Moreover, tracker information will be made available to the Level 1 trigger. For this purpose CMS will introduce pT modules, a dedicated module design in which the clusters from two closely spaced sensors can be correlated and high momentum tracks can be selected. This talk will motivate and introduce the concept of the CMS Outer Tracker upgrade and will give an overview of the ongoing R&D activities.
