We use a simulated large-volume scintillation detector modeled on the Super-Kamiokande experiment, fully implementing this detector in RAT/Geant4. This allows us to extract authentic spectra for the experimental signature of the [Beta]+/EC decay in 124Xe, paving the way for future sensitivity studies. We also consider the relevance of next-generation techniques for background discrimination, specifically particle identification based on counting Cherenkov photons. We find that discrimination between [Beta] and [Beta] particles is readily possible in experiments run at the 1.25 MeV energy scale and also see evidence for the possibility of distinguishing between [Beta]+ and [Beta]- particles via their Cherenkov signatures","abstract_html":"In this thesis, we consider the [Beta]+/EC decay of 124Xe and take the first steps towards characterizing a hypothetical experiment to detect it, making use of techniques traditionally employed in neutrinoless double beta decay experiments.
