Status and Performance of the AMoRE-I Experiment on Neutrinoless Double Beta Decay

Abstract

AMoRE is an international project to search for the neutrinoless double beta decay of Mo-100 using a detection technology consisting of magnetic microcalorimeters (MMCs) and molybdenum-based scintillating crystals. Data collection has begun for the current AMORE-I phase of the project, an upgrade from the previous pilot phase. AMoRE-I employs thirteen (CaMoO4)-Ca-48depl.-Mo-100 crystals and five (Li2MoO4)-Mo-100 crystals for a total crystal mass of 6.2 kg. Each detector module contains a scintillating crystal with two MMC channels for heat and light detection. We report the present status of the experiment and the performance of the detector modules.
