SUSY Mu+VBF Trigger Performance with 2017 Data
/CMS Collaboration
SUSY Mu+VBF trigger performance results for 13 TeV from CMS are presented. The results are based on the 36.7 fb$^{-1}$ of data obtained in 2017 and include the efficiencies as a function of various variables reconstructed with the offline version of the CMS software. [...]

Expected Leakage Current Distribution in BPix based on Measurements in a Thermal Mock-Up
/CMS Collaboration
This Detector Performance Summary shows results from detailed temperature studies on a mock-up of a half-layer of the CMS Phase-1 pixel detector using realistic heat loads and identical CO$_{2}$ cooling circuits. From the measured temperature distribution the consequences on leakage currents have been evaluated..

Phase-I Pixel ROC Thresholds and DC-DC Converter Characterization in 2018
/CMS Collaboration
This Detector Performance Summary shows the measured thresholds of the CMS phase-1 pixel readout chip after the commissioning in 2018 as well as in June 2018. We also present the results of the characterization campaign of the extracted DC-DC converters in the LHC year-end technical stop 2017/2018..

CMS Tracker Performance results for full Run 2 Legacy reprocessing
/CMS Collaboration
During the LHC Long Shutdown 2, the CMS experiment started a collaboration-wide effort to re-calibrate the data and optimize the simulation, reconstruction and analysis software in order to reprocess the data collected during LHC Run 2 with uniform software and detector calibrations (Legacy processing). \\
This note collects performance results of the tracker detector alignment obtained using the updated Legacy software and calibration for the data collected by CMS during the three years period 2016, 2017 and 2018, and corresponding to an integrated luminosity of about 140/fb. [...]

Muon Tracking Efficiency for 2018 dataset using Tag and Probe method
/CMS Collaboration
The muon tracking efficiency has been measured using the tag and probe technique on di-muon resonances $ Z \longrightarrow \mu^{+} \mu^{-} $ and $ J/\psi \longrightarrow \mu^{+} \mu^{-} $ for both ``all tracks" and ``tracker-only seeded tracks" for 2018 dataset with an integrated luminosity 59 fb$ ^{-1}$..

Background measurements in the CMS DT chambers during LHC Run 2
/CMS Collaboration
Characterizing background helps to understand its trend and sources, and to devise mitigation measures to prevent detector ageing, especially in view of luminosity increase.
During LHC Run2, the background in the CMS Drift Tubes (DT) was monitored both by means of online anode current measurements and offline analysis. Results are shown in terms of trends vs LHC instantaneous luminosity and of spatial distributions..

Monitoring and Modelling of the Radiation Damage of the CMS Phase-1 Pixel Detector in the Barrel Region
/CMS Collaboration
This Detector Performance Summary shows the comparison between measurement and modellation of the development of sensor leakage currents as well as the depletion voltages for all the layers in the CMS Phase-1 Pixel detector in the barrel region after the end of LHC Run-2. In addition to that, a first rough measurement of the z dependence of the sensor leakage currents is presented, which was taken after the end of LHC Run-2..
