Integration Tests with Module Prototypes for the Phase- 2 Upgrade of the CMS Outer Tracker — •Lea Stockmeier, Alexander Dierlamm, Ulrich Husemann, and Stefan Maier — Institute of Experimental Particle Physics (ETP), Karlsruhe Institute of Technology (KIT)

To deal with the increased luminosity of the HL-LHC, the CMS experiment will be upgraded until 2028. During this Phase-2 Upgrade, the CMS Outer Tracker will be equipped with modules each assembled with two silicon sensors. Depending on the position in the tracker, these silicon sensors are pixel or strip sensors. The modules with two strip sensors are called 2S modules while those assembled of one macro-pixel and one strip sensor are called PS modules. In the endcap region these modules are mounted on structures called ``dees``. Four dees will be combined to one ``double-disc`` which provides the hermetic coverage of one detector plane.

During the prototyping phase of the modules, integration tests are performed with the purpose of testing the integration procedure itself as well as the module functionality on the final detector structures. For example, the electronic noise of the modules can be taken to check the performance of the modules on the supporting structures.

This talk summarizes an integration test performed at DESY (Hamburg) with six PS and seven 2S modules on a prototype dee in cooperation with other CMS working groups.
