Introduction

This package contains the algorithms to generate the Geant 4 based shower parametrisation libraries. The generation process is a two step process. First, full Geant 4 simulation is run with single particles. The information about the hits in the sensitive calorimeter detectors is store using the ShowerLib::StepInfo class. In a second step the collected hits are clusterd and collected into a frozen shower library using the ShowerLib::ShowerLib class.

Class Overview

The LArG4GenShowerLib package contains of following algorithms:

• LArG4GenShowerLib: clustering and collecting hits into shower library
• TestActionShowerLib: collecting of hit information in full Geant 4 simulation

The data structure of the the shower library is contained in the LArG4ShowerLib package. The entry point is the ShowerLib::ShowerLib class. The hit information collected by the test action is contained in the LArG4ShowerLib package. The entry point is the ShowerLib::StepInfoCollection class.

Job Options

For both algorithms dedicated job options are supplied which are used by the script generateShowerLib.py.

• LArG4GenShowerLib_generateHits_topoptions.py: configuration of single particle gun for hit generation
• LArG4GenShowerLib_testActionShowerLib_joboptions.py: configuration of test action for hit generation
• LArG4GenShowerLib_combine_topoptions.py: configuration of hit clustering and output options
• LArG4GenShowerLib_setupCalo_joboptions.py: configure calorimeter
• LArG4GenShowerLib_setup_joboptions.py: configure general LArG4GenShowerLib algorithm properties

The list of properties for each algorithm can be found here:

• LArG4GenShowerLib::LArG4GenShowerLib

Scripts

The whole shower library generation process can be done in one step using the generateShowerLib.py script. For the options see the help function of the script.

Default Settings
