Description
AMoRE experiment has been searching for the neutrinoless double beta decay in Mo-100, using a cryogenic calorimetric technique with Mo-containing scintillating crystals. The detector module features hybrid detection of the phonon and scintillation signals from the particle interaction, based on metallic magnetic calorimeters (MMCs). The phonon channel determines the energy with high resolution, while the light channel enables the particle identification, leading to effective background suppression.
As we are targeting the highly sensitive detection limits, further enhancement of the light detector performance has been pursued to improve the baseline energy resolution, light collection and time response. Since the random pile-up of the two neutrino double beta decay is expected to become a dominant background in future experiments, the effort to address this issue will be one of the important milestones. In this poster, we present a detailed characterization of the AMoRE light detectors and discuss related R&D efforts.
