| contents | The T2K ND280 upgrade aims to reduce the systematic uncertainty of the CP-violating phase, $δ_{CP}$, to reject non-CP violation hypothesis at $3σ$ confidence level. A crucial component of the ND280 upgrade, alongside the Super Fine Grained Detector (SuperFGD) and two High-Angle Time Projection Chambers (TPCs), is the Time-of-Flight (ToF) detector, which significantly enhances background rejection and particle identification capabilities. The ToF detector features six modules in a cube configuration, each with 20 plastic scintillator bars measuring $\text{220}\times\text{12}\times\text{1}\,\text{cm}^3$ and is equipped with Silicon Photomultiplier (SiPM) arrays at both ends to capture scintillation light. This letter outlines the modelling of the detector response and the signal reconstruction process. |
