Pandora软件开发工具包和算法库提供了模式识别逻辑，这对重建液氩时间投影室探测器中的粒子相互作用至关重要。Pandora是ProtoDUNE-SP使用的主要事件重建软件，ProtoDUNE-SP是深地下中微子实验远探测器的原型。位于CERN的ProtoDUNE-SP暴露在带电粒子测试束中。本文给出了一个概述的潘多拉重建算法，以及它们如何被定制用于在ProtodUNE-SP。在复杂的事件与众多的宇宙射线和光束背景粒子，模拟重建和识别效率触发测试束粒子是80%以上的大多数粒子类型和光束动量组合。具体地说，模拟的1 GeV/c带电π介子和质子被正确地重建和识别，效率分别为86.1±0.6%和84.1± 0.6%。测试梁数据测得的效率被证明是在5%以内的模拟预测。
The Pandora Software Development Kit and algorithm libraries provide pattern-recognition logic essential to the reconstruction of particle interactions in liquid argon time projection chamber detectors. Pandora is the primary event reconstruction software used at ProtoDUNE-SP, a prototype for the Deep Underground Neutrino Experiment far detector. ProtoDUNE-SP, located at CERN, is exposed to a charged-particle test beam. This paper gives an overview of the Pandora reconstruction algorithms and how they have been tailored for use at ProtoDUNE-SP. In complex events with numerous cosmic-ray and beam background particles, the simulated reconstruction and identification efficiency for triggered test-beam particles is above 80% for the majority of particle type and beam momentum combinations. Specifically, simulated 1 GeV/c charged pions and protons are correctly reconstructed and identified with efficiencies of 86.1±0.6% and 84.1±0.6%, respectively. The efficiencies measured for test-beam data are shown to be within 5% of those predicted by the simulation.
