## Abstract

The four 10 kt Liquid Argon Time Projection Chambers (LArTPCs) of the future DUNE experiment will enable precise measurements of the oscillation parameters and the discovery of CP violation for leptons, thanks to their excellent 3D imaging capabilities and calorimetric capabilities. One or more modules of the DUNE detector may exploit a Dual Phase (DP) LArTPC that, relying on the extraction of the charge produced in the liquid volume and its subsequent multiplication in argon gas, may offer a robust and competitive signal-to-noise ratio and a fully active volume. In 2018 and 2019, the ProtoDUNE experiment at CERN will validate the designs of the DUNE far detector, showing the feasibility of large scale Dual-Phase LArTPC and providing precious insight on the DUNE physics potential.
