Combining high precision calorimetry with scalability to the multi-kiloton level, the Liquid Argon Time Projection Chamber (LAr TPC) has proven to be an attractive technology for long baseline neutrino oscillation experiments. An extensive R&D program for LAr TPCs at the ten-kiloton level is currently underway in the context of the Deep Underground Neutrino Experiment (DUNE). The DUNE far detector, located at the Sanford Underground Research Facility in South Dakota, USA, will measure the oscillated neutrino flux at a baseline of 1300 km with four 10 kiloton LAr TPC modules. Two different technologies are being explored for this purpose: single phase and dual phase LAr TPCs. The dual phase technology allows to amplify the charge signal in gas argon, offering several advantages over the single phase. The first large scale dual phase LAr TPC with an active volume of 3x1x1 m3 has been operated at CERN in 2017. Another prototype with an active volume of 6x6x6 m3 will be commissioned by the end of 2018, paving the way for DUNE. This poster will give a detailed overview of the different reconstruction stages for dual phase LAr TPC data. Furthermore, results on the liquid argon purity, charge readout uniformity and charge-light matching for the 3x1x1 m3 detector are presented.
