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 ${}^{100}$Mo 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 ${}^{48depl.}$Ca${}^{100}$MoO${}_4$ crystals and five Li${}_2$${}^{100}$MoO${}_4$ 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.
