摘要:

AgReO 4微量热计计划再次用于下一代的中微子质量量热实验,灵敏度低至0.2 eV。了解和描述系统不确定性的所有可能来源至关重要。在这项工作中,我们专注于其中两个来源,这已在10个探测器的米兰AgReO 4阵列实验(MIBETA):a)的固态β环境精细结构(BEFS)观察到的第一次在AgReO 4; b)的检测器的能量响应内部β事件,这已被调查与专用测量使用44 Ti伽马源。讨论了由于对这两个方面的认识不充分而对中微子质量实验可能产生的影响。

英文摘要:

AgReO4 microcalorimeters are planned to be used again in the next generation of calorimetric neutrino mass experiments with sensitivity down to 0.2 eV. The understanding and characterization of all possible sources of systematic uncertainties is crucial. In this work we focus on two of these sources, which have been studied in the 10 detectors of the Milano AgReO4 array experiment (MIBETA): a) the solid-state Beta Environmental Fine Structure (BEFS) observed for the first time in AgReO4; b) the detector energy response for internal beta events, which has been investigated with a dedicated measurement using a 44Ti gamma source. The possible effects on neutrino mass experiments due to the incomplete understanding of these two aspects are discussed.
