Summary: New results on the radiopurity of a 3.4-kg NaI(Tl) crystal scintillator operated in the SABRE proof-of-principle detector setup show the lowest ever achieved potassium contamination and breakthrough background rate in the crystal active veto setup, dominated by Pb-210. Ongoing developments in crystal manufacture aim at further reducing background rates to levels suitable for next-generation NaI(Tl) detector arrays for the direct detection of dark matter particles.

Summary: The optical and scintillation properties of undoped and Ce-doped (Gd0.4Lu0.6)(8)Sr-2(SiO4)(6)O-2 crystals were investigated. XRD patterns confirmed the absence of impurity phases in Ce-doped samples, while undoped samples contained impurity phases. Emission from Ce3+ transitions was observed in the spectra of Ce-doped samples. The scintillation light yields of 0.5% and 1.0% Ce-doped samples were approximately 230 and 620 ph/5.5 MeV-alpha, respectively.

Summary: To measure the quantities of special nuclear materials (SNM) accurately, phoswich detectors combining Gd3Ga3Al2O12:Ce and CsI:Tl scintillators were used. These detectors have high efficiency, sensitivity, and discrimination ability for thermal neutrons and gammas from spontaneous fission of Pu and other isotopes in the presence of high gamma background. The linearity of low energy gammas stopped completely in 1mm thick disc of GGAG can be distinguished from high energy gammas, and the setup also shows good linearity for thermal neutron detection over a wide range. The quantity of test samples can be accurately calculated using the measured calibrated plot.

Summary: 0.1%, 0.5%, and 1% Er-doped Bi4Ge3O12 (BGO) single crystals were grown by the floating zone method. The crystals exhibited photoluminescence and scintillation properties, with emission peaks at 550 nm and 1540 nm due to the 4f-4f transitions of Er3+, as well as an emission band across 400-600 nm due to the transitions of Bi3+. The photoluminescence quantum yields of the NIR emission increased with the Er doping concentration. The scintillation decay time constants were consistent with the known values of Er3+. The crystals showed afterglow effects and a linear relationship between near-infrared luminescence intensity and X-ray exposure dose rate.

Summary: In this study, charge compensation by co-doping Na+ ions at the Ca2+ sites of Ce-doped LiCaAlF6 single crystals was performed to prevent the generation of cation vacancies. As a result, improved radiation resistance and increased light yield under neutron irradiation were achieved. On the other hand, the use of Al metal as a substitute for AlF3 in Eu-doped LiCaAlF6 and Eu-doped LiSrAlF6 single crystals significantly increased the effective segregation coefficient keff of Eu2+ ions.

Summary: The growth conditions for producing high-quality ZnWO4:Sm single crystals using the Czochralski method were determined in this study. The role of Sm impurity in bubble formation in a ZnWO4 single crystal was discussed, and the segregation coefficient of Sm3+ ions in the ZnWO4 single crystal was estimated to be 0.023. The effect of non-isomorphic substitution of Sm3+ for Zn2+ ions on the ZnWO4 crystal lattice parameters was investigated. The X-ray luminescence spectra of ZnWO4:Sm3+ crystals were also discussed. Two ZnWO4 crystals doped with samarium enriched in Sm-148 and Sm-149 isotopes were successfully obtained using the established growth technique, demonstrating its feasibility and reliability for producing detectors for rare nuclear processes studies.

Summary: The cross section of coherent elastic neutrino-nucleus scattering (CEvNS) was measured using a CsI[Na] scintillating crystal in a high flux of neutrinos. The COHERENT Collaboration achieved the most precise measurement of CEvNS yet, which is consistent with the standard model. The results placed leading constraints on neutrino nonstandard interactions and tested lepton flavor universality and weak mixing angle.

Summary: Core-collapse Supernovae (SNe) are highly energetic events that release the star's binding energy in the form of neutrinos. RES-NOVA aims to detect neutrinos from astrophysical sources using a ton-scale array of cryogenic detectors made from archaeological lead, which offers high sensitivity to all neutrino flavors. By utilizing archaeological lead as a sensitive target material, RES-NOVA can achieve an ultra-low background level and potentially deploy the first cm-scale neutrino telescope for astrophysical investigations.

Summary: This study investigates the X-ray luminescence spectra, thermally stimulated luminescence, and thermally stimulated conductivity of undoped cesium iodide (CsI) crystal to better understand the emission processes in this material. The results suggest that the low-energy band at 2.2 eV is due to residual impurities, while the bands at 3.6 and 4.3 eV are attributed to the intrinsic emission of CsI. The increase in luminescence at 4.3 eV above 70 K is caused by the release of trapped electrons interacting with Vk centers, and the observed ionic conductivity above 250 K is influenced by uncontrolled impurities.

Summary: This paper presents measurements of the relative decrease of light output during irradiation of small plastic scintillator tiles read out by silicon photomultipliers. The study found substantial temporary damage during low-temperature irradiation, regardless of oxygen concentration and wrapping material. The wrapping material had an impact on the relative light loss, with the 3M(TM) Enhanced Specular Reflector Film showing the largest loss. The light loss was less at warmer temperatures and similar to that in standard atmosphere with 3% oxygen concentration. Evidence of a plateau in the radical density was seen for the data at 0 degrees C.
