Combined Beam Tests of EMEC/HEC/FCal (CBT-EC2):
Information about useful runs


This page contains information about runs taken during the combined beam tests of EMEC, HEC and FCal modules in 2004. Analysed runs belong to: The aim of the analysis was to select useful runs, sorting out bad, strange or suspicious ones. Main reasons of rejection of runs were the following:

Finally, 1982 runs were selected. Here is information about useful runs.
WARNING: Selection of runs is based mainly on analysis of random events. There still can be problems in physics events.


Data files

All data, taken during the testbeam, are available on CASTOR at CERN:

/castor/cern.ch/atlas/atlascerngroupdisk/det-larg/cbt-ec2/phys

Information on how to access data files is available on the ATLAS page: "CASTOR pools and access rules". (Use xrdcp instead of rfcp. It works under SLC5.)

Data files of all selected runs (daq_beamDAQ_H6_000????_file01.data, where ???? stand for a run number) are kept at RZG:

/pnfs/rzg.mpg.de/mpp/atlas/user/akiryuni/cbt2/data/
or
/pnfs/rzg.mpg.de/mpp/atlas/user/jerdmann/ctb.14.0.0/data/

(files from the last directory should be used only if they are absent in the previous one).

Random files

Random files (randoms_????.root) are ROOT-files, containing signals in all 698 calorimeter channels in random events. They are available
at RZG: /pnfs/rzg.mpg.de/mpp/atlas/user/akiryuni/cbt2/randoms/
at MPI: /.at/hec-data/kiryunin/cbt2/randoms/
These files are used to model noise in simulated samples. In total, there are 2.423.843 random events.

Noise files

Noise files (sigmas_????.dat) are ASCII-files, containing noise sigmas for all 698 calorimeter channels. Sigmas are results of the fit of signal distributions in random events to a Gaussian. Files are available
at RZG: /pnfs/rzg.mpg.de/mpp/atlas/user/akiryuni/cbt2/sigmas/
at MPI: /.at/hec-data/kiryunin/cbt2/sigmas/
These files are used by the SimpleNoiseTool during the reconstruction.
