Assembly and Test Procedures of 2S modules for the future Outer Tracker of the Phase-2 Upgrade of the CMS Experiment — •Stefan Maier, Tobias Barvich, Bernd Berger, Alexander Dierlamm, Alexander Droll, Umut Elicabuk, Jan-Ole Müller-Gosewisch, Ulrich Husemann, Roland Koppenhöfer, Markus Klute, Gani Kösker, Thomas Müller, Marius Neufeld, Hans Jürgen Simonis, Pia Steck, Lea Stockmeier und Florian Wittig — Institute of Experimental Particle Physics, Karlsruhe Institute of Technology

In preparation for the High Luminosity LHC, the entire tracker of the CMS experiment will be exchanged within the Phase-2 Upgrade until 2027. The new outer tracker will be made of approximately 13000 silicon sensor modules called 2S modules (consisting of two parallel silicon strip sensors) and PS modules (one pixel and one strip sensor combined in a module). These modules provide tracking information to the Level-1 trigger by correlating the hit information of both sensor layers and, thus, allowing to discriminate charged particles by their transverse momentum. To guarantee successful operation of the CMS detector at the HL-LHC, the production of the outer tracker modules has to fulfil strict requirements. The talk will summarize the various assembly and test concepts for the large scale production of 2S modules and will present the latest module prototypes.
