Abstract: We integrated the detector and the readout electronics for a new inner-station TGC system at the ATLAS experiment and evaluated the performance in preparation for the HL-LHC. The TGC detectors installed in the end-cap inner stations of the ATLAS detector will be upgraded from doublet to triplet chambers to improve the selectivity of the first-level muon trigger. The challenging structure of fitting a triplet within the same envelope as the doublet necessitates integration tests with the readout electronics. The detector and readout electronics from early production were integrated, and the measurements showed an acceptable noise level and a detection efficiency of 92-94% for each layer. Additionally, the trigger circuit was developed requiring coincidences in two or more layers for this detector, which was confirmed through the functional simulation.
