English: The TPC for the ND280 Upgrade of T2K is now fully operational and taking cosmic data at CERN. In addition to the importance of the detector itself for the Near Detector of T2K, the detection technology used for this machine (Encapsulated Resistive Anode Micromegas, ERAM). Two detectors of the NP07 project have been fully developed and commissioned at CERN: a Time-Of-Flight detector and a High-Angle TPC, currently taking cosmic data. They are in building 887 (Prevessin) and 182 (Meyrin). The Tokai to Kamiokande (T2K) experiment is a long-baseline neutrino experiment taking data since 2010. The neutrino beam is detected on two sites, the near detector complex close to the neutrino production point, and Super-Kamiokande in a distance of 300 km. The ND280 detector is one of the near detectors and has the purpose to characterize the beam before oscillation as also the measurement of interaction cross sections. Both is crucial to reduce the systematic uncertainties. To improve the latter further, the T2K collaboration decided in 2016 an upgrade of ND280 which includes the installation of a novel scintillator tracker, two time projection chambers and a time of flight system. This upgrade, in combination of an increase of the neutrino beam power from currently 500 kW to 1.3 MW, will roughly increase the statistics by a factor 4 and reduce the systematic uncertainties from 6% to 4%. The new subdetectors are currently being assembled and will be installed in 2022. The upgraded ND280 will also serve as near detector of the next generation long-baseline neutrino oscillation experiment Hyper-Kamiokande.
