Most conventional noble liquid detectors employ scintillation light as either a timing signal for a TPC or as a calorimetric measurement, or both. Its relative amplitude and timing on multiple detectors can also be used to approximately locate an interaction.
Scintillation imaging goes a step further. By developing a suitable optical system, coupled with finely segmented SiPM arrays, it is...
We consider the relativistic photon diffusion equation for unbounded media of Lemiux et al, to which we present an analytical solution in terms of the physical parameters of a LArTPC. We account for photon absorption at the boundaries through physical considerations, instead of a boundary value problem. Then we compare our results to several Geant4 simulations and analyze the results and...
In this work, the algorithm for simulating scintillation is examined, particularly the one used in the Geant4 toolkit. Being widely adopted in experimental particle physics, Geant4 became the standard for detector simulation, including those based on noble elements, which in turn are used due to their scintillation properties. Geant4 algorithms for scintillation physics are 20 years old and...
Neutrons from the cavern in the DUNE Far Detector present a significant background in the low energy regime of a few MeV. Additionally, neutrons appear as the final state product in many low energy neutrino interaction channels in argon. Identifying the neutron capture signature is crucial for the DUNE low energy program. Neutron capture in argon releases a cascade of gamma rays, with the...
