Overview

   A Cosmic run is testing the response of the modules of four SCT barrel cylinders and some of the TRT modules. For TRT barrel 2+2 sectors (top+bottom) tilted vertically by 20 degrees will be connected and for SCT barrel will be connected 504 modules. It is therefore a good opportunity to train and test the tracking and alignment algorithms in real conditions with cylindrical geometry.



Data Samples

InnerDetector-Cosmic-00 (Before 11.4.0)

  • Take a look to the InDetCommissioning TWiki

InnerDetector-Cosmic-01 (11.4.0 - 11.5.0)

One can only reconstruct simulated RDOs which were digitized with the new TRT digitization which is the default in 11.4.0

  • Simulation files can be found at /castor/cern.ch/user/c/cescobar/cosmics/sim/11.4.0
  • Digitized data can be found at /castor/cern.ch/user/c/cescobar/cosmics/dig/11.4.0

ATLAS-Commissioning-InDet-01 (12.0.0)

SCT_GeoModel Updated

  • Simulation files can be found at /castor/cern.ch/user/c/cescobar/cosmics/12.0.0/sim
  • Digitized data can be found at /castor/cern.ch/user/c/cescobar/cosmics/12.0.0/dig

There is a known bug: residuals phi dependence (fix below)


ATLAS-Commissioning-InDet-01 (12.0.1)
