DT Slice Test 2021 Calibration Stability plots

A "Slice Test", corresponding to one sector of the CMS Drift Tube (DT) detector, was installed during the LHC Shut Down 2, to develop and test the DT electronics designed for LHC Run 4 (Phase 2). An accurate calibration of the produced signals is needed to guarantee the optimal time resolution of future Local Trigger. The first step of calibration is the inter-channel equalization, to be performed within each DT chamber, using dedicated Test-Pulse runs: pulses are injected in all wires simultaneously and the resulting Phase 2 signals are recorded. The analysis presented here shows that the new system is stable in time, the maximum average differences between different runs amounting to 0.5 ns. The same procedure will also be used in the future as an effective monitoring tool.
