DUNE Optical Detector Digitization and Backtracking Update. Jason Stock & Juergen Reichenbacher South Dakota School of Mines and Technology Single Phase Photon Detection 2018-07-16 You Inst Logo
Updates I am making changes to the photon New Code simulation in DUNE to allow us to DuneObj • track how photons at an optical DuneObjDumpers • detector turn into signals on SiPMs. OpDetDivRec.{ccx,h} • Updated Code OpDetDigitizerDUNE_module.cc • PhotonBackTracker • ● New data products (DUNE only for now) ● Changes to the Digitizer simulation ● Comparison of final reco. ● Changes to the PhotonBackTracker 2 Jason Stock | Radiological Simulation You Inst Logo
OpDetDivRec The DivRecs. Record how photons are deposited on individual channels durring the OpDetDigitizer stage. Why not art::Assn? Code changes were more • extensive. Recovery in the backtracker was • more complicated Fig 1. Diagram of the OpDetDivRec structure Bigger change than I had time to • (From in progress technical note on BackTracking in DUNE) make for minimal payout. Might still do so in the future • (After art events are exposed to services). 3 Jason Stock | Radiological Simulation You Inst Logo
Changes to the Digitizer Configurable input ( • - PhotonsLite || OpDetBacktrackerRecord) New output (only for processing • OpDetBacktrackerRecords) - OpDetDivRec IMPORTANT. Fcl flag for using • OpDetBTRs will over-ride LarG4Properties. Fig 2.
