Producing simulation for ACDC
This page documents the procedure on how to produce
.sim and then
.digi files for the VELO testbeam.
A description of two ACDC geometries has been defined:
- ACDC2 describes three modules of the VeloRight
- ACDC3 describes 10 modules sitting in vacuum behind a 4mm aluminum beam window. A Pb segmented target is added along the beam line.
In both these cases, all other objects -- RF foil, vacuum tank and the
VeloLeft -- have been removed from the XML description.
Running Gauss and Boole
A set of option files have been produced to run the standard executables to produce Velo ACDC data. These option files are maintained in a seperate package,
Velo/VeloACDC. So first get this package and then run Gauss is the same are normal:
source ~lhcbvelo/scripts/startACDC.csh <myACDCinstallation>
This will take you the
job subdirectory of
VeloACDC. From here launch Gauss and Boole with
runGauss <acdc> <nEvents> <full filename less the extention>
runBoole <acdc> <cc> <full filename less the extention>
eg.
runGauss ACDC3 $MYSCRATCHAREA/testfile
runBoole ACDC3 HP1 $MYSCRATCHAREA/testfile
To modify initial beam parameters, edit $VELOACDCOPTS/GaussParticleGun.opts
To modify number of events generated, edit $VELOACDCOPTS/Gauss.opts
