DUNE Neutrino Flux File Documentation
- File Formats
- Fluxes are available in
several formats including dk2nu trees that contain information about all neutrinos generated in
the beamline and neutrino energy histograms that were obtained from these trees.
- The
trees have large file sizes and are available in limited quantities here; larger
samples are available to DUNE collaborators with access /pnfs/dune/persistent area at Fermilab or in some cases upon request.
- In most cases, There are files for both neutrino mode (FHC) and antineutrino mode (RHC).
- Histograms
- Each histogram file will typically contain fluxes for the near detector (ND) located 574 m downstream of the start of Horn 1 and the far detector (FD) located 1297 km downstrea
- Histograms are available in two different formats -- a .root file containing flux histograms and a GLoBES flux input file.
- The GLoBES files have units of nus / GeV / m^2 / POT; the columns of those files correspond to the neutrino energy at bin center, nue flux, numu flux, nutau flux, nuebar flux.
- Software Versions
- The fluxes were generated with various patches of G4LBNF version v3r5; the specific version is in the filenames.
- The histogram files also contain Neutral Current and Charged Current event ratess, which were
