The Advanced Molybdenum-based Rare process Experiment (AMoRE) aims to search for neutrinoless double beta decay (0$\nu\beta\beta$) of $^{100}$Mo with $\sim$100 kg $^{100}$Mo-enriched molybdenum embedded in cryogenic detectors a dual heat and light readout. At the current, pilot stage AMoRE project we employ six calcium molybdate crystals total mass 1.9 kg, produced from $^{48}$Ca-depleted ($^{48\textrm{depl}}$Ca$^{100}$MoO$_4$). simultaneous detection heat(phonon) scintillation (photon)...

Soda-lime-silicate glasses with the compositions of (65-x)SiO2-25Na2O-10CaO-xDy2O3 (where x = 0.0, 0.10, 0.30, 0.50 and 1.00 mol %) were prepared by melt-quenching technique characterized. The density (ρ) molar volume (VM) obtained found to increase increasing Dy2O3 content. Such behaviour was accounted for differences between atomic weight radii Si Dy ions. rare-earth ion concentration (N) ionic radius (rp) calculated. absorption spectra Dy3+ doped soda-lime-silicate glass correspond...
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 (Advanced Mo-based Rare process Experiment) project is a series of experiments that use advanced cryogenic techniques to search for the neutrinoless double-beta decay \mohundred. work being carried out by an international collaboration researchers from eight countries. These searches involve high precision measurements radiation-induced temperature changes and scintillation light produced in ultra-pure \Mo[100]-enriched \Ca[48]-depleted calcium molybdate...
