Commissioning and Performance of the CMS Pixel Tracker with Cosmic Ray Muons
(Journal of Instrumentation, 2010)
The pixel detector of the Compact Muon Solenoid experiment consists of three barrel layers and two disks for each endcap. The detector was installed in summer 2008, commissioned with charge injections, and operated in the ...
Commissioning of the CMS High-Level Trigger with cosmic rays
(Journal of Instrumentation, 2010)
The CMS High-Level Trigger (HLT) is responsible for ensuring that data samples with potentially interesting events are recorded with high efficiency and good quality. This paper gives an overview of the HLT and focuses on ...
Performance of the CMS drift tube chambers with cosmic rays
(Journal of Instrumentation, 2010)
Studies of the performance of the CMS drift tube barrel muon system are described, with results based on data collected during the CMS Cosmic Run at Four Tesla. For most of these data, the solenoidal magnet was operated ...
Fine synchronization of the CMS muon drift-tube local trigger using cosmic rays
(Journal of Instrumentation, 2010)
The CMS experiment uses self-triggering arrays of drift tubes in the barrel muon trigger to perform the identification of the correct bunch crossing. The identification is unique only if the trigger chain is correctly ...
Precise mapping of the magnetic field in the CMS barrel yoke using cosmic rays
(Journal of Instrumentation, 2010)
The CMS detector is designed around a large 4 T superconducting solenoid, enclosed in a 12 000-tonne steel return yoke. A detailed map of the magnetic field is required for the accurate simulation and reconstruction of ...
