Description
The Deep Underground Neutrino Experiment (DUNE), the next generation long-baseline neutrino experiment, comprises a suite of Near Detectors and four Far Detectors based on the Liquid Argon TPC technology which is enhanced by a powerful Photon Detection System (PDS) that records the scintillation light emitted in Argon.
The two observables generated from energy deposition by particles in liquid Argon are charge and light. Therefore, a calorimetric measurement to determine the energy of neutrino beam events can be performed by exploiting the complementarity of the two.
The visible energy can also be estimated by using charge information alone, however, only electrons escaping recombination and reaching the wire planes can be used so corrections must be applied for this loss. As charge and light are anti-correlated and their sum is directly proportional to the total energy deposited the advantage of using both and is that the correction for recombination is no more necessary. When using the light information we profit as well from a detailed end-to-end simulation of our photodetection system.
Doping liquid Argon with Xenon allows to shift the 128nm light emitted by Argon to a longer wavelength (175 nm) improving its detection. In this poster we will present results obtained for calorimetric measurements in the DUNE horizontal-drift Far Detector by combining charge and light in pure liquid Argon as well as the comparison with a 10ppm Xenon doping of liquid Argon.
