Abstract
The near detector ND280 of the T2K experiment will be upgraded in 2022 with the aim of measuring precisely CP violation in neutrinos. The ND280 upgrade consists of the installation of 3 new sub-detector types including SuperFGD, a novel neutrino active target concept. SuperFGD (Super-Fine-Grained-Detector) will have 2 million 1 × 1 × 1cm3 plastic scintillator cubes forming a cube array of 184 × 56 × 192 cm3. Each of the cubes will be intersected by 3 orthogonal WLS fibers with an MPPC on one end. Thanks to its super-fine segmentation, high light yield, and excellent time resolution, great particle identification (PID) capabilities are expected. Since 2018, a set of prototypes have been exposed to particle beams (charged tracks and neutrons) to test this concept. Here the results concerning the particle identification (PID) capabilities using the last prototype are presented.
