The T2K experiment is the long-baseline experiment that observed the oscillation channel from a muon neutrino to an electron neutrino. Recently T2K has shown a hint of CP violation in neutrinos, by measuring different appearance probabilities of neutrino and antineutrinos. In order to achieve the required large statistics and reduce the effects of the systematic uncertainties, a vigorous program to upgrade the T2K Near Detector (ND280) is being undertaken. The upgrade consists in replacing one of the sub-detectors, the P0D, with two horizontal time projection chambers (TPC) and a horizontal fully active scintillator target, allowing 3D tracking, located in between.

Abstract
The T2K experiment is the long-baseline experiment that observed the oscillation channel from a muon neutrino to an electron neutrino. Recently T2K has shown a hint of CP violation in neutrinos, by measuring different appearance probabilities of neutrino and antineutrinos. In order to achieve the required large statistics and reduce the effects of the systematic uncertainties, a vigorous program to upgrade the T2K Near Detector (ND280) is being undertaken. The upgrade consists in replacing one of the sub-detectors, the P0D, with two horizontal time projection chambers (TPC) and a horizontal fully active scintillator target, allowing 3D tracking, located in between. The project for the new TPC field cages was developed within the T2K Collaboration by the Padova, Bari and LNL INFN groups.
