Description
The Deep Underground Neutrino Experiment (DUNE) is a cutting-edge experiment for neutrino science and proton decay studies. The single-phase liquid argon prototype detector at CERN (ProtoDUNE-SP) is a crucial milestone for DUNE that will inform the construction and operation of the first, and possibly subsequent 17-kt DUNE far detector modules. We have studied the response of DUNE LArTPC prototype detector ProtoDUNE-SP to test beam positrons via both ionization and scintillation signals. We searched for (anti) correlation between fluctuations of both scintillation and ionization in liquid argon, on event-by-event basis. Preliminary results, to be presented at the conference, reveal anti-correlated statistical fluctuation between scintillation and ionization in liquid argon.
