Description
The SuperFGD (Super Fine-Grained Detector) is a part of the ND280 near
detector complex for the T2K and Hyper-Kamiokande experiments. The
SuperFGD is a fully active and highly granular scintillator neutrino
detector. It consists of approximately 2 million scintillation cubes,
which allow for the reconstruction of particles traveling in all
directions. A good understanding of the SuperFGD response is crucial
for detailed Monte Carlo simulations and systematics estimation for
further physics analyses. This poster covers the selection of
atmospheric muons stopped inside the sensitive volume of the detector,
including their decays. Muons were selected by applying geometrical
constraints and searching for subsequent electrons or positrons. The
reconstructed spectrum of the Michel e-/e+ is useful as another source
of energy scale determination. Reconstruction of Compton electrons
following positron annihilation allows for the evaluation of the
SuperFGD effective low energy threshold
