Description
The T2K near detector ND280 is currently being upgraded to prepare the second phase of data taking T2K-II, with the purpose of confirming at 3σ level if CP symmetry is conserved or violated in the neutrino oscillations. For this upgrade, new detectors are currently being installed including so-called High-Angle Time Projection Chambers. They are instrumented with Encapsulated Resistive MicroMegas detectors as readout plane which are used to spread the charge on several pads thus allowing for a better reconstruction of the track position.
To take benefit of this feature, a new reconstruction algorithm was developed using the ResNet50 Convolutional Neural Network to extract the track parameters and perform particle identification. This technique was trained and tested on simulations proving the capabilities of the CNN to reconstruct the particles momentum and perform particle identification.
