Simulations for the HEC Prototype Module (Version 1)

This is a working area: changes are possible

A prototype module of the ATLAS hadronic end-cap calorimeter was tested at CERN in 1996. The corresponding simulations, based on the version 1 of the HEC test-beam Monte Carlo software (HEC-TB-MC), were fulfilled at MPI (Munich) in 1996-97.

These software is installed now in the following area:
/home/iws109a1/atlas/lhc/testbeam/version_1

Examples of macros to run jobs and of corresponding datacards: /home/iws109a1/atlas/lhc/testbeam/version_1/job

Simulated particles: muons, electrons, pions
1000 events per each energy/space point

Simulated data (banks GEOM, KINE, HITS, DIGI) are kept on tapes at MPI. In all tables below the size of data-files is given for unzipped files.

Banks with cell energies and MWPC hits: /at/data1/tb_mc_1/*.bank
Size of each file - 4.4 Mbytes

What can be found at CERN?

All files with the code were copied to the HEC test-beam disk at CERN. They can be found under the directory: /afs/cern.ch/atlas/testbeam/HEC/mc/soft/version_1
To get a working (at CERN) version of the code, it is necessary at least to make changes in the install-kumac.

Files with data, obtained with the version 1 of the HEC-TB-MC software, are not available at CERN computers.
