Description
Optical imaging of alpha tracks in scintillators have been demonstrated in recent years. The imaging of particle tracks has potentials in rare event searches, such as the neutrinoless double-beta decay search. This talk presents the observation and data analyses of alpha particle tracks in a GAGG crystal scintillator using a scientific CMOS camera mounted on an optical microscope. Results on the energy resolution, position resolution, track length and dE/dx are discussed. The alpha track data together with Geant4 simulations show the potential to extend this method to MeV electron tracking in scintillators, which can be useful in identifying double-beta decays.
