论文摘要
低能光谱仪（蜡烛）研究中微子和暗物质的氟化钙搜索使用CAF $ _2 $ scintillator Array的$^{48} $ CA的无中微子双β衰减。 $^{48} $ ca的高Q值在4,272 kev时使我们能够达到非常低的背景条件，但是，由于缺乏标准的高能$γ$ -RAY -RAY -RAY-RAY -RAY源，因此在校准检测器的Q值区域时会造成困难。因此，我们已经开发了一个基于$γ$ ray发射的新颖校准系统，该系统由$^{28} $ si，$^{56} $ fe和$^{58} $ ni nuclei上的中子捕获。在本文中，我们报告了新校准系统的开发以及高达9 MeV的蜡烛的能量校准结果。
CAlcium fluoride for the study of Neutrinos and Dark matters by Low-energy Spectrometer (CANDLES) searches for neutrino-less double beta decay of $^{48}$Ca using a CaF$_2$ scintillator array. A high Q-value of $^{48}$Ca at 4,272 keV enabled us to achieve very low background condition, however, at the same it causes difficulties in calibrating the detector's Q-value region because of the absence of a standard high-energy $γ$-ray source. Therefore, we have developed a novel calibration system based on $γ$-ray emission by neutron capture on $^{28}$Si, $^{56}$Fe and $^{58}$Ni nuclei. In the paper, we report the development of the new calibration system as well as the results of energy calibration in CANDLES up to 9 MeV.
