设计并建造了一个有效质量为185 g的双相氩时间投影室（TPC），用于反冲方向性（ReD）实验。ReD项目的目的是研究基于氩的TPC通过柱状复合对直接暗物质搜索的感兴趣的能量范围（20-）内的核反冲的方向灵敏度。的关键新功能的ReD TPC是一个读出系统的基础上，低温硅光电倍增管（SiPM），这是雇用和连续运行的第一次在氩TPC。在6个月的时间里，ReD TPC在各种操作条件下使用射线和中子源进行了调试和表征，证明了光学传感器的出色稳定性和结果的可重复性。测得TPC的闪烁增益和电离放大分别为光电子/光子和光电子/电子。电离闪烁信号的比率（S2/S1），有助于积极识别的候选人诱导的WIMPs定向信号，已被调查的核和电子反冲。在183 V/cm的漂移场，S2/S1分散度为12%的核反冲约60-，相比之下，18%的电子反冲沉积60 keV的能量。这里报告的检测器性能满足所需的要求，以实现主要的科学目标的ReD实验中的方向性效应，由于柱状重组的搜索。在LAr的复合概率的唯象参数化，并用于建模的依赖性闪烁淬灭和电荷产量的漂移场之间的电子反冲50-500 keV和字段高达1000 V/cm。
A double-phase argon Time Projection Chamber (TPC), with an active mass of 185 g, has been designed and constructed for the Recoil Directionality (ReD) experiment. The aim of the ReD project is to investigate the directional sensitivity of argon-based TPCs via columnar recombination to nuclear recoils in the energy range of interest (20–) for direct dark matter searches. The key novel feature of the ReD TPC is a readout system based on cryogenic Silicon Photomultipliers (SiPMs), which are employed and operated continuously for the first time in an argon TPC. Over the course of 6 months, the ReD TPC was commissioned and characterised under various operating conditions using-ray and neutron sources, demonstrating remarkable stability of the optical sensors and reproducibility of the results. The scintillation gain and ionisation amplification of the TPC were measured to bephotoelectrons/photon andphotoelectrons/electron, respectively. The ratio of the ionisation to scintillation signals (S2/S1), instrumental for the positive identification of a candidate directional signal induced by WIMPs, has been investigated for both nuclear and electron recoils. At a drift field of 183 V/cm, an S2/S1 dispersion of 12% was measured for nuclear recoils of approximately 60–, as compared to 18% for electron recoils depositing 60 keV of energy. The detector performance reported here meets the requirements needed to achieve the principal scientific goals of the ReD experiment in the search for a directional effect due to columnar recombination. A phenomenological parameterisation of the recombination probability in LAr is presented and employed for modeling the dependence of scintillation quenching and charge yield on the drift field for electron recoils between 50–500 keV and fields up to 1000 V/cm.
