Poster Neutrino oscillation Poster


Currently, long-baseline neutrino experiments use detectors that induce multiple kinds of neutrino-nuclear interactions. This can produce neutral particles in the final state such as neutrons. Those neutrons are largely missed in operating experiments. A 3D projection scintillator tracker called Super-FGD will be a component of the upgraded off-axis near detector of T2K. It is made of 1 cm optically isolated scintillator cubes read by three wavelength-shifting fibers going through cubes in the x y and z directions. It promises the capability of detecting neutron-induced charged particles and reconstructing neutron kinematic energy using the Time-of-Flight technique. To prove neutron reconstruction capabilities two prototypes have been constructed and exposed to the neutron beamline at Los Alamos National Lab (LANL) in 2019 and 2020. In this poster, the details of their construction, the experimental setup at LANL, and the event reconstruction developed for the analysis of the data taken during the test beam will be discussed.
