This article reports on a cryogenic setup that can be used for multifunctional experimental purposes. The temperature of the setup can be set from 10 K to 300 K. Different kinds of experiments were carried out in this experimental setup such as (1) luminescence emission, light yield, and decay time measurement under excitation of 266 nm laser and 280 nm LED sources, (2) thermoluminescence (TL) measurement under an x-ray excitation source, (3) scintillation property measurements such as light output, energy resolution, and decay time under 137Cs (662 keV γ-rays) and 241Am (5.4 MeV α) isotope sources, and (4) scintillation measurement under a 90Sr beta source through the continuous single-photon counting technique. The luminescence and scintillation properties of various molybdate and tungstate crystals such as CaMoO4, Na2Mo2O7, Pb2MoO5, CdWO4, and ZnWO4 are characterized and reported in the present work. The TL measurement of a CaMoO4 crystal is carried out from 10 K to 300 K, and various kinetic parameters such as order of kinetics, frequency factor, activation energy, and figure of merit are calculated for different TL peaks. As the temperature goes down from room to 10 K, the light yield of all studied crystals increases. Since the light yield of the crystal increases as temperature decreases toward 10 K, this experimental setup can be used for the characterization of luminescence and scintillation properties of a single crystal for rare event searches such as neutrinoless double-beta decay and dark matter.

用于单晶发光和闪烁特性多功能表征的低温装置

本文报告了一种可用于多功能实验目的的低温装置。该装置的温度可设置为 10 K 至 300 K。在该实验装置中进行了不同种类的实验，例如（1）在 266 nm 激光和 280 nm 激光激发下的发光发射、光产率和衰减时间测量LED 光源，(2) X 射线激发源下的热释光 (TL) 测量，(3) 闪烁特性测量，例如在 137Cs（662 keV γ 射线）和 241Am（5.4 MeV）下的光输出、能量分辨率和衰减时间α) 同位素源，以及 (4) 通过连续单光子计数技术在 90Sr β 源下的闪烁测量。各种钼酸盐和钨酸盐晶体如CaMoO4、Na2Mo2O7、Pb2MoO5、CdWO4、和 ZnWO4 在目前的工作中被表征和报道。CaMoO4 晶体的 TL 测量在 10 K 至 300 K 范围内进行，并针对不同的 TL 峰计算各种动力学参数，例如动力学阶数、频率因子、活化能和品质因数。随着温度从室温下降到 10 K，所有研究的晶体的光输出都会增加。由于晶体的光产额随着温度向 10 K 降低而增加，因此该实验装置可用于表征单晶的发光和闪烁特性，用于罕见事件搜索，例如无中微子双 β 衰变和暗物质。并针对不同的 TL 峰计算各种动力学参数，例如动力学阶数、频率因子、活化能和品质因数。随着温度从室温下降到 10 K，所有研究的晶体的光输出都会增加。由于晶体的光产额随着温度向 10 K 降低而增加，因此该实验装置可用于表征单晶的发光和闪烁特性，用于罕见事件搜索，例如无中微子双 β 衰变和暗物质。并针对不同的 TL 峰计算各种动力学参数，例如动力学阶数、频率因子、活化能和品质因数。随着温度从室温下降到 10 K，所有研究的晶体的光输出都会增加。由于晶体的光产额随着温度向 10 K 降低而增加，因此该实验装置可用于表征单晶的发光和闪烁特性，用于罕见事件搜索，例如无中微子双 β 衰变和暗物质。
