Outline

  • Particle gun MC of pions and protons
  • Studying the MC true energy deposited in

protodune

  • Quantifying energy associated to primary,

and to neutral secondaries (photons, neutrons)

  • Examining how much of the true energy ends

up as a reconstructed hit, and reconstructed clusters by 4 reconstruction modules

– lineclusterdc, linecluster, pandoradc, pandora

larsoft workflow

  • Using dunetpc v05_13_00

– protodune_v2 geometry

  • protoDUNE_gensingle.fcl

– Pion or proton, 0.1 – 3.0 GeV – x: 118.106 cm, y: 395.649 cm, z: 0 cm

  • protoDUNE_g4single.fcl
  • protoDUNE_detsim_single.fcl

– Optical simulation is off, to save time

  • protoDUNE_reco.fcl
  • No cosmics / multiparticle events

Analysis

  • For now, only looking at the true energy

deposits

  • Associating each energy deposit to

– Primary – Neutrons – and subsequent daughters – Photons – and subsequent daughters

  • Calculating the fraction of energy deposited

into those three categories

  • Calculating how much of this true energy

ends up in a reconstructed hit

Summary

  • ~100% of primary energy deposit is

reconstructed in hits

  • ~40% of neutron energy is lost
  • ~30% of photon energy is lost
  • Even more energy is unclustered
  • Pandora doing worse than linecluster
  • No difference between ‘dc’ and non-‘dc’
