NuDoubt++ searches for neutrinoless double beta plus decay with opaque scintillators. These scintillators have a very short scattering length but long absorption length and can be used to confine the light emitted after particle interactions in a small detector volume. A dense grid of wavelength shifting optical fibers deployed in the scintillating material and equipped with SiPMs then enables the detection of a significant fraction of the emitted photons. This approach allows efficient identification of particles as well as a precise reconstruction of the particles energy.
Photon propagation in such a detector can be approximated using diffusion models. However, this does not take into account shadowing effects of the deployed fibers, which can lead to significant differences in the expected photon counts. This effect can be corrected using MC simulations. In this presentation, the event reconstruction based on a diffusion model is shown.
