GENIE at FNAL¶

This is the wiki page for GENIE work being done at FNAL

Official GENIE site¶

The full GENIE project is located at: http://www.genie-mc.org

The source code can be found on GitHub: https://github.com/GENIE-MC

Documentation¶

GENIE as a UPS product¶

The GENIE code is available from genie.hepforge.org, but needs to be compiled in a manner consistent with other products it depends on (ROOT, LHAPDF, etc) and with any framework it might be used within (e.g. ART). Many of the FNAL experiments use UPS to share these installations.

• UPS installations of GENIE at FNAL
• Auxillary UPS GENIE products

Cross-section splines¶

In order to use GENIE for event generation one must have generated cross-section splines for any and all desired combinations of neutrino an flavor and nuclear isotope. Versions of these spline files that are adequate for the FNAL experiments are distributed via UPS.

• UPS products genie_phyopt and genie_xsec
• List of available pre-calculate spline sets: https://cdcvs.fnal.gov/redmine/projects/nutools/wiki/GENIE_Configuration_Files

Flux handling for GENIE and FNAL experiments¶

Event generation for realistic experimental setups relies on a non-trivial characterization of the neutrino flux. The GNuMIFlux code exists to handle many of the data products of the NuMI flux simulations. The GSimpleNtpFlux format is a simplified ntuple containing the bare minimum of data for neutrino rays; such files can be derived from GNuMIFlux interpretations of the beam simulations evaluated at a given detector location.

• GNuMIFlux code and config
• Generating GSimpleNtpFlux files
• Manipulating GSimpleNtpFlux files

Future "flux" file are to be migrated to using the dk2nu ntuple format: https://cdcvs.fnal.gov/redmine/projects/nusoftart/wiki/Dk2nu

Running gevgen_fnal¶

In many cases genie event generation will occur as a stage embedded in the art framework. Information on that can be found as part of the nutools and/or nugen project ( https://cdcvs.fnal.gov/redmine/projects/nutools/wiki and https://cdcvs.fnal.gov/redmine/projects/nugen ).
