Development of a GUI for a test stand for silicon detector modules of CMS 2S modules for the Phase-2 Upgrade of the CMS Tracker — •Anna Becker, Lutz Feld, Waclaw Karpinski, Katja Klein, Martin Lipinski, Alexander Pauls, Nicolas Röwert, and Michael Wlochal — 1. Physikalisches Institut B, RWTH Aachen

The CMS Collaboration is developing so-called 2S modules for the second phase of the CMS tracker upgrade. This upgrade will enable the CMS experiment to utilize the high luminosity provided by the future HL-LHC. One of the module assembly centres is RWTH Aachen, where 1000 2S modules will be built. During the production, a test stand based on a probe station is needed to monitor the quality of the silicon sensors in between the various assembly steps. To simplify, secure and accelerate the workflow a GUI for this test stand has been developed. After each assembly step various control measurements are performed. This GUI enables a user-friendly automatization, especially of the sensor's leakage current measurement and its surface inspection. Moreover, various environmental conditions are monitored to guarantee constant measurement conditions. Both the GUI itself and selected measurement results of 2S modules built at RWTH Aachen are presented.
