Tips and Tricks for Software
Using the Grid and the Batch Cluster
Have a look at GridForDummies as a short introduction on how to copy to and from the Grid.
Have a look at BatchClusterForDummies as a short introduction on how to run jobs on our local cluster.
Have a look at GenerateSteeringFiles for the automatic generation of steering files.
Detector Model
I have used the ILD_00 model. The basic mokka model is described in http://www-flc.desy.de/ldcoptimization/tools/mokkamodels.php?model=ILD_00. I have attached the gear file I have used for my analysis, and some more information can be found in the ILD Letter of Intent.
Most important for my analysis is the ECAL. It is a silicon-tungsten sandwich calorimeter with 30 active layers and 5*5 mm^2 cell size.
Event Generation
The SUSY particle spectrum is calculated by SPheno, all interactions and decays are simulated with Whizard. See
for further information. Here you can find my SPheno input file and my WHiZard input file.
create Mokka file
For my PhD thesis, I used Mokka installation is v06-07-p01.
Some general geant4 documentation can be found in https://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/ForApplicationDeveloper/html/
The installation and usage of Mokka is documeted in the Mokka page in this wiki
The installation and modification of Geant4, especially how to add particles, is described in the Geant4 page in this wiki
reconstruct Mokka files with Marlin
For my thesis I used Marlin installation: /afs/desy.de/group/it/ilcsoft/v01-06/Marlin/v00-10-04/
The detector geometry is described in a gear file.
This has to be included in the steering file, see EventReconstruction. Calibration constants for the LDCCaloDigi-processor and how to obtain them is explained in CalorimeterCalibration
In general particles can be reconstructed with the PandoraPFA processor, an example steering file is delivered with each Pandora distribution. More information can found at EventReconstruction.
More advanced, but detector geometry dependent photon clustering can be done with the Predrag's photonfinder kit.
