液氩时间投影室（LArTPC）提供了一个强大的和优雅的方法来测量中微子相互作用的性能超过几十兆电子伏的三维事件成像具有良好的空间分辨率。LArTPC已被深地中微子实验（DUNE）选为远探测器技术，它将在中微子质量有序和CP破坏的研究以及质子衰变和超新星中微子的寻找中发挥重要作用。位于费米实验室的35吨原型具有DUNE远探测器正在考虑的许多先进技术，例如膜低温恒温器，冷电子学，带缠绕导线的阳极平面组件（阿帕），读出闪烁光子的硅光电倍增管，触发宇宙射线μ子的闪烁体计数器。35吨LArTPC的高质量数据对于理解许多物理效应非常重要，例如由杂质引起的衰减，扩散，空间电荷以及μ子，质子和中性π子的量热响应。
Liquid argon time projection chambers (LArTPCs) provide a robust and elegant method for measuring the properties of neutrino interactions above a few tens of MeV by providing 3D event imaging with excellent spatial resolution. LArTPCs have been chosen by the Deep Underground Neutrino Experiment (DUNE) as the far detector technology and it will play an essential role in the studies of neutrino mass ordering and CP violation as well as searches for proton decays and supernova neutrinos. The 35 ton prototype, located at Fermilab, featured many advanced technologies being considered by the DUNE far detector, such as the membrane cryostat, cold electronics, anode plane assembly (APA) with wrapped wires, silicon photomultipliers to readout scintillation photons, scintillator counters to trigger cosmic ray muons. The high quality data in the 35-ton LArTPC are important to the understanding of many physics effects such as the attenuation caused by impurities, diffusion, space charge, and calorimetric response of muons, protons and neutral pions.
