论文摘要

我们报告了使用$^{83 \ Mathrm {M}} $ KR源的CENNS-10液体氩检测器的准备和校准测量。 $^{83 \ mathrm {M}} $ kr原子在$^{83} $ rb源中生成的$ kr原子通过注入AR循环环引入检测器中。然后观察到$^{83 \ mathrm {m}} $ kr在检测器体积中产生的9.4 keV和32.1 keV转换电子。该校准源允许表征CENNS-10检测器的低能响应,并适用于其他低能阈值检测器。在总$^{83 \ Mathrm {M}} $ 41.5 KeV的$^{83 \ Mathrm {M}} $ 41.5 KEV的总$^{83 \ Mathrm {Mathrm {Mathrm {Mathrm {Mathrm {Mathrm {Mathrm {83 \ Mathrm {83 \ Mathrm {Mathrm {Mathrm {Mathrm {Mathrm {Mathrm {83 \ syrm {83 \%$)的能源分辨率为9 $ \%$。我们进行了一项分析,使用9.4 keV和32.1 keV的两个转换电子分别校准检测器

We report on the preparation of and calibration measurements with a $^{83\mathrm{m}}$Kr source for the CENNS-10 liquid argon detector. $^{83\mathrm{m}}$Kr atoms generated in the decay of a $^{83}$Rb source were introduced into the detector via injection into the Ar circulation loop. Scintillation light arising from the 9.4 keV and 32.1 keV conversion electrons in the decay of $^{83\mathrm{m}}$Kr in the detector volume were then observed. This calibration source allows the characterization of the low-energy response of the CENNS-10 detector and is applicable to other low-energy-threshold detectors. The energy resolution of the detector was measured to be 9$\%$ at the total $^{83\mathrm{m}}$Kr decay energy of 41.5 keV. We performed an analysis to separately calibrate the detector using the two conversion electrons at 9.4 keV and 32.1 keV
