LHCb OT Straw-Tube Modules in mCBM: Integration and First Beam-Time Results — •Luca Schramm for the CBM collaboration — GSI Helmholtzzentrum für Schwerionenforschung GmbH, Planckstraße 1, 64291 Darmstadt

Several of the former LHCb Outer Tracker (OT) straw tube modules were successfully installed and evaluated in the mini CBM (mCBM) test environment. The CERN-LHCb collaboration donated the OT straw tube detector to GSI. The aim is to install it as part of the Forward Tracking Systems in FAIR experiments such as PANDA and recently also as part of the Muon Detector of the CBM.

During the spring of 2025, the LHCb modules were operated under varied high-voltage and threshold settings during heavy-ion beam tests at GSI to assess performance stability. The contribution will present the beam-test setup and results obtained. A joint PANDA-CBM cooperation developed simulation and reconstruction software to enable the analysis of beam-test data. The results demonstrate consistent straw tube performance across the tested conditions, confirming the detector's readiness for integration into either experiment.
