 Quality Certification 4 (QC4) for RE4 Performance Plots /CMS Collaboration The installation of two new wheels in the end-caps of the RPC system (RE4) is expected during LHC Long Shutdown (LS1). The RE4 upgrade project consists of 72 Super Modules (SM), each one made with 2 RPC chambers, for a total of 144 double-gap RPC chambers.

 CASTOR very forward calorimeter performance in 2013 data in pPb and pp collisions /CMS Collaboration CASTOR has taken data since the beginning of LHC operation in 2009. In 2012 the calorimeter has been upgraded with radiation hard PMTs. [...] CMS-DP-2013-035; CERN-CMS-DP-2013-035.- Geneva : CERN, 2013 - 23 p. Fulltext: PDF;

 Centrality determination for pPb data 2013 /CMS Collaboration Centrality is very important for defining the collision system size in heavy ion collisions. It provides a tool for selecting events in a similar way in different experiments and facilitates the comparison of experimental results and theoretical calculations [...] CMS-DP-2013-034; CERN-CMS-DP-2013-034.- Geneva : CERN, 2013 - 17 p.

 BCM1F Performance in 2012 /CMS Collaboration The Fast Beam Condition Monitor BCM1F consists of 8 single-crystal CVD 5 mm x 5 mm diamonds positioned 1.8 m on either side of the interaction point at a radius of 4.5 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.

 Collision induced background in the DT chambers /CMS Collaboration The spatial distribution of background produced by colliding beams in the DT chambers was determined using 2012 data and found to be compatible with expectations. Within the available range, the rates increase linearly with increasing instantaneous beam luminosity.. CMS-DP-2013-031; CERN-CMS-DP-2013-031.- Geneva : CERN, 2013 - 7 p. Fulltext: PDF;

 Optimization of the Gas System in the CMS RPC Detector at the LHC /CMS Collaboration The Resistive Plate Chambers (RPC) are a part of the muon spectrometer for the Compact Muon Solenoid (CMS) experiment at Large Hadron Collider (LHC). RPCs are ionizing-particle detectors consisting of two gaps filled up with gas. [...] CMS-DP-2013-030; CERN-CMS-DP-2013-030.- Geneva : CERN, 2013 - 9 p. Fulltext: PDF;
