Double-beta decays of $^{100}$Mo from the 6.0195-year exposure of a 6.914 kg high-purity sample were recorded by the NEMO-3 experiment that searched for neutrinoless double-beta decays. These ultra-rare transitions to $^{100}$Ru have a half-life of a

Autor: Azevedo, C. D. R., Baeza, A., Chauveau, E., Corbacho, J. A., Díaz, J., Domange, J., Marquet, C., Martínez-Roig, M., Piquemal, F., Veloso, J. F. C. A., Yahlali, N.

In this work we present simulation results for a modular tritium in-water real-time monitor. The system allows for scalability in order to achieve the required sensitivity. The modules are composed by 340 uncladed scintillating fibers immersed in wat
