The High Luminosity upgrade of the LHC (HL-LHC) is foreseen to increase the instantaneous luminosity by a factor of five over the present LHC nominal value. The resulting, unprecedented requirements for background monitoring and luminosity measurements create the need for new high-precision instrumentation at CMS, using radiation hard detector technologies. This contribution discusses the implications of using the Tracker Endcap Pixel Detector for online measurements of luminosity and beam-induced background. The suitability of the TEPX detectormfor these tasks is explored and implementations for separate triggering and readout systems are explained.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
