 Measurement of hit position resolution in the DT chambers using 2012 data. /CMS Collaboration The hit resolution is computed from the width of the distribution of the observed distance between any reconstructed hit and the fitted segment it belongs to. The present measurement is based on collision data collected in 2012.. CMS-DP-2014-004; CERN-CMS-DP-2014-004.- Geneva : CERN, 2014 - 7 p. Fulltext: PDF;

 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;
