AMoRE is an international project to search for the neutrinoless double beta decay of $^{100}$Mo using a detection technology consisting magnetic microcalorimeters (MMCs) and molybdenum-based scintillating crystals. Data collection has begun current AMORE-I phase project, upgrade from previous pilot phase. AMoRE-I employs thirteen $^\mathrm{48depl.}$Ca$^{100}$MoO$_4$ crystals five Li$_2$$^{100}$MoO$_4$ total crystal mass 6.2 kg. Each detector module contains with two MMC channels heat light...
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...

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 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.

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 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.

Abstract The second phase of the Advanced Mo-based Rare process Experiment (AMoRE-II) searches for a neutrino-less double-beta decay 100 Mo. A background level in region interest 3034 ± 10 keV is required to be lower than -4 count/(keV kg year). Neutrons can generate signals by gamma-ray emitting reactions with AMoRE-II detector materials. Thermal neutron shields will installed inside and outside lead shield reduce flux shielding system. radioactivity inner thermal must low because requires...
AMoRE-II is the second phase of Advanced Molybdenum-based Rare process Experiment aiming to search for neutrino-less double beta decay 100Mo isotopes using ~ 200 kg molybdenum-containing cryogenic detectors. The needs keep background level below 10-5 counts/keV/kg/year with various methods maximize sensitivity.
