Test Beam Analysis of a Silicon-Strip Module for the CMS Phase-II Tracker Upgrade — •Chun Cheng — DESY, Hamburg, Germany

The foreseen Large Hadron Collider upgrade is expected to deliver an integrated luminosity that is one order of magnitude larger after 2027. Rare processes and new phenomena may be observed in this high luminosity era. The Phase-II Outer Tracker upgrade of the CMS experiment is required to surmount higher radiation and increased event rate. Transverse momentum (PT ) discrimination is introduced in the design and will contribute to the Level-1 Trigger. A CMS silicon strip module with PT discrimi- nation concept was built by the DESY Outer Tracker group and has undergone a test beam experiment at the test beam DESY facility.

The talk will mainly focus on DESY 2S module production, sensor studies, data acquisi- tion scheme and give a summary of the results from the recent test beam measurements.
