摘要:

设想在基准体积中以15 bar的压力容纳5 kg氙气,NEXT- White(NEW)装置是目前世界上最大的使用电致发光放大的高压氙气TPC。它也是NEXT-100探测器的1:2比例模型,计划于2019年开始搜索136光年的$ββ0ν$衰变。两个探测器都使用位于透明阴极后面的光电倍增管平面来测量事件的能量。他们还可以在阳极后面的硅光电倍增器平面的帮助下,重建TPC稠密气体中带电径迹的轨迹。两种探测器共有一个复杂的气体系统,可以提供保证长电子寿命所需的高气体纯度。NEXT-White自2017年10月以来一直在西班牙的Canfranc地下实验室(LSC)运营。本文介绍了检测器和相关的基础设施。

英文摘要:

Conceived to host 5 kg of xenon at a pressure of 15 bar in the fiducial volume, the NEXT- White (NEW) apparatus is currently the largest high pressure xenon gas TPC using electroluminescent amplification in the world. It is also a 1:2 scale model of the NEXT-100 detector scheduled to start searching for $ββ0ν$ decays in 136Xe in 2019. Both detectors measure the energy of the event using a plane of photomultipliers located behind a transparent cathode. They can also reconstruct the trajectories of charged tracks in the dense gas of the TPC with the help of a plane of silicon photomultipliers located behind the anode. A sophisticated gas system, common to both detectors, allows the high gas purity needed to guarantee a long electron lifetime. NEXT-White has been operating since October 2017 at the Canfranc Underground Laboratory (LSC), in Spain. This paper describes the detector and associated infrastructures.
