Tracking POG plot results on 2015 data /CMS Collaboration
The new conditions of Run II with respect to Run I (center of mass energy and bunch spacing) call for a complete characterization of the detectors from the beginning, in order re-calibrate the whole system and verify its performances. The plots shown below focus on the performance analysis of the CMS tracking system from both direct and indirect measurements..

Initial Report of the Fast Timing Working Group /CMS Collaboration
A preliminary set of results highlighting the unique capabilities of fast-timing for resolving information from individual collisions at the High-Luminosity LHC (HL- LHC) is presented. These results explore the possibilities made available by using fast timing to enhance the reconstruction and physics capabilities of the CMS detector in terms of pileup mitigation and searches for new physics.

Results on CASTOR Performance during LHC Run 2 /CMS Collaboration
Results on various aspects of the performance of the CASTOR calorimeter in LHC Run 2 are presented. This includes the alignment, calibration and triggers of the detector. The intercalibration of the gains of the fine mesh PMT's using beam-halo muons is discussed, this in combination with results of a study on the noise and baseline. [...]

Tracking and Luminosity Calibration of the PLT /CMS Collaboration
The Pixel Luminosity Telescope (PLT) is one of the newest additions to the CMS detector for the LHC Run II data taking period. On each side of the CMS detector it consists of eight 3-layer telescopes based on silicon pixel detectors that are placed around the beam pipe viewing the interaction point at small angle. [...]

Machine Induced Background with BCM1F 2015 /CMS Collaboration
The Fast Beam Condition Monitor BCM1F consists of 24 single-crystal CVD 5 mm x 5 mm diamonds positioned 1.8 m on either side of the interaction point at a radius of 6.5 cm from the beam pipe. The signal is read out, shaped by a frontend ASIC, and converted to an optical signal which is then transmitted to the backend electronics in USC55. [...]

The CMS Beam Halo Monitor Detector System /CMS Collaboration
A new Beam Halo Monitor (BHM) detector system has been installed in the CMS cavern to measure the machine-induced background (MIB) from the LHC. This background originates from interactions of the LHC beam halo with the final set of collimators before the CMS experiment and from beam gas interactions. [...]

Performance of the CMS Beam Halo Monitor /CMS Collaboration
The CMS Beam Halo Monitor has been successfully installed in the CMS cavern in LHC Long Shutdown 1 for measuring the machine induced background for LHC Run II. The system is based on 40 detector units composed of radiation hard synthetic quartz Cherenkov radiators coupled to fast photomultiplier tubes for a direction sensitive measurement. [...]
