AMoRE searches for the neutrinoless double beta decay using 100 kg of enriched Mo100. Scintillating molybdate crystals coupled with a metallic magnetic calorimeter operate at milli-Kelvin temperatures to measure energy electrons emitted in decay. AMoRE-I is demonstrator full-scale AMoRE, operated Yangyang Underground Laboratory over two years. The exposure was 8.02 year (or 3.89 kgMo100 year), and total background rate near Q value 0.025±0.002 counts/keV/kg/year. We observed no indication...
The AMoRE-II experiment will search for the 0 νββ decay of 100 Mo nuclei using molybdate crystal scintillators, operating at milli-Kelvin (mK) temperatures, with a total 80 kg Mo. background goal is 10 –4 counts/keV/kg/year in region interest around Q-value 3,034 keV. To achieve this level, rate signals arising from emissions produced by decays radioactive impurities detector and shielding materials must be strictly controlled. do this, concentrations such are measured controlled through...

This paper describes the preparation of radiopure lithium carbonate powder for needs low-background research, in particular, AMoRE-II, second phase a search neutrinoless double-beta decay (0νDBD) 100 Mo isotope using over kg contained 200 ultra-pure Li 2 MoO 4 bolometric crystals. About 150 pure CO 3 is required to synthesize The desired radiopurity 40 K below mBq/kg, and Th/U Ra are at few mBq/kg. Several commercially available powders were tested with ICP-MS HPGe detectors Center...
The AMoRE collaboration searches for neutrinoless double beta decay of $^{100}$Mo using molybdate scintillating crystals via low temperature thermal calorimetric detection. early phases the experiment, AMoRE-pilot and AMoRE-I, have demonstrated competitive discovery potential. Presently, AMoRE-II featuring a large detector array with about 90 kg isotope, is under construction.This paper discusses baseline design characterization lithium cryogenic calorimeters to be used in modules. results...
We report a study on the background of Advanced Molybdenum-Based Rare process Experiment (AMoRE), search for neutrinoless double beta decay (\znbb) $^{100}$Mo. The pilot stage experiment was conducted using $\sim$1.9 kg \CAMOO~ crystals at Yangyang Underground Laboratory, South Korea, from 2015 to 2018. compared measured $\beta/\gamma$ energy spectra in three experimental configurations with results Monte Carlo simulations and identified sources each configuration. replaced several detector...
AMoRE-II aims to search for neutrinoless double beta decay with an array of 423 Li$_2$$^{100}$MoO$_4$ crystals operating in the cryogenic system as main phase Advanced Molybdenum-based Rare process Experiment (AMoRE). AMoRE has been planned operate three phases: AMoRE-pilot, AMoRE-I, and AMoRE-II. is currently being installed at Yemi Underground Laboratory, located approximately 1000 meters deep Jeongseon, Korea. The goal reach up $T^{0\nu\beta\beta}_{1/2}$ $\sim$ 6 $\times$ 10$^{26}$ years,...
AMoRE searches for the signature of neutrinoless double beta decay $^{100}$Mo with a 100 kg sample enriched $^{100}$Mo. Scintillating molybdate crystals coupled metallic magnetic calorimeter operate at milli-Kelvin temperatures to measure energy electrons emitted in decay. As demonstration full-scale AMoRE, we conducted AMoRE-I, pre-experiment 18 crystals, Yangyang Underground Laboratory over two years. The exposure was 8.02 kg$\cdot$year (or 3.89 kg$_{\mathrm{^{100}Mo}}\cdot$year) and total...
