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...

Abstract This paper presents a comparative study of various light detectors (LDs) developed for different phases the AMoRE neutrinoless double beta decay experiment. We analyze performance these in terms characteristics such as time response, collection, and energy resolution. Our primary focus is on evaluating AMoRE-II detector (LD), which integral to forthcoming It found that type LDs outperform other previous types. The best-performing LD exhibits FWHM resolution 99 eV, 185 182 493 eV...
We developed an X-ray detector using 36 arrays, each consisting of a 64-pixellated yttrium oxyorthosilicate (YSO) scintillation crystal and 64-channel multi-anode photomultiplier tube. The was designed to detect X-rays with energies lower than 10 keV, primarily the aim localizing gamma-ray bursts (GRBs). YSO crystals have no intrinsic background, which is advantageous for increasing low-energy sensitivity. fabricated integrated into UBAT, payload Ultra-Fast Flash Observatory (UFFO)/Lomonosov...
