Description
AMoRE is an international project to search for the neutrinoless double beta decay of 100Mo in enriched Mo-based scintillating crystals using metallic magnetic calorimeters in a mK-scale cryogenic system. The project aims at operating the detector in a zero-background condition to detect the extremely rare decay event in the region of interest near 3.034 MeV. The simultaneous measurement of phonon and photon signals is performed at a few tens of mK temperatures to achieve a high resolution and good background rejection. AMoRE-I has been running with thirteen 48depletedCa100MoO4 and five Li2100MoO4 crystals. Since the beginning of the experiment in Sep. 2020, we have accumulated and analyzed more than 200 days of physics data. We will present preliminary results of the detector performance, the background level, and the half-life limit from the latest AMoRE-I data analysis.
