论文摘要

该手稿描述了Los Alamos中子科学中心(LANSCE)中的中子束中迷你船长液体氩检测器的调试,这导致了Argon中高能源中子相互作用的首次测量。迷你船长探测器由时间投影室(TPC)组成,其中包含一个伴随的光电层管(PMT)阵列,该阵列密封在充满液体 - 阿贡填充的低温恒温器中。在操作过程中,液体氩气经常纯化并在闭环循环中再循环。据报道,探测器子系统的规格和组装及其在中子束中的性能概述。

This manuscript describes the commissioning of the Mini-CAPTAIN liquid argon detector in a neutron beam at the Los Alamos Neutron Science Center (LANSCE), which led to a first measurement of high-energy neutron interactions in argon. The Mini-CAPTAIN detector consists of a Time Projection Chamber (TPC) with an accompanying photomultiplier tube (PMT) array sealed inside a liquid-argon-filled cryostat. The liquid argon is constantly purified and recirculated in a closed-loop cycle during operation. The specifications and assembly of the detector subsystems and an overview of their performance in a neutron beam are reported.
