This paper reports on a measurement of electron-ion recombination in liquid argon in the ICARUS liquid argon time projection chamber (LArTPC). A clear dependence of recombination on the angle of the ionizing particle track relative to the drift electric field is observed. An ellipsoid modified box (EMB) model of recombination describes the data across all measured angles. These measurements are used for the calorimetric energy scale calibration of the ICARUS TPC, which is also presented. The impact of the EMB model is studied on calorimetric particle identification, as well as muon and proton energy measurements. Accounting for the angular dependence in EMB recombination improves the accuracy and precision of these measurements.
Experimental observation of an extremely high electron lifetime with the ICARUS-T600 LAr-TPC
ICARUS T600探测器是经过多年研发活动实现的最大液态氩时间投影室（LAr-TPC），已在INFN Gran Sasso地下实验室安装并成功运行3年。最重要的问题之一是需要在液态氩中具有极低的残余电负性杂质含量，以便以非常小的衰减沿漂移路径传输由电离粒子产生的自由电子。氩再循环和纯化系统所采用的解决方案在氩纯度和超过15 ms的自由电子寿命方面实现了令人印象深刻的结果，相当于约万亿分之20的当量O2污染，这是涉及LAr-TPC的任何未来项目和更高探测器质量尺度的开发的里程碑。

LArIAT（Liquid Argon In A Testbeam）旨在表征液氩时间投影室（LArTPC）对现有和计划中的探测器中经常被视为~1 GeV中微子相互作用终态产物的粒子的响应。该实验使用ArgoNeuT低温恒温器及其翻新的170升有效体积TPC放置在费米实验室测试束设施（FTBF）的高能π介子束产生的可调三级束线中。TPC被修改以适应冷读出电子设备和光收集系统。第一次运行发生在2015年5月至6月，收集的数据将有助于理解电子复合行为，簇射重建，粒子识别，μ子符号确定，氩中的π介子和K介子相互作用，以及闪烁光用于量热法。
