论文摘要
我们设计，开发和部署了一个分布式传感器网络，旨在观察日本沿海地区的冬季雷云和闪电的高能电离辐射（主要是伽马射线）。从2015年开始，我们在Ishikawa县和Niigata县总共安装了15个以上的地面探测器系统，并在2015年底至2019年初的四个冬季中累积了551天的观察时间。在此期间，我们的系统记录了51次来自Thundercloud and Lightning和Lightning的伽马射线辐射事件。从这种前所未有的数据中获得的科学结果的亮点包括在闪电中发现光核反应，该反应产生了中子和正电子以及伽马射线，以及对粒子加速器和雷霆队发出γ射线发出的生命周期的更深入的见解。本文审查了我们实验的客观，方法和结果，并压力其仪器。
We designed, developed, and deployed a distributed sensor network aiming at observing high-energy ionizing radiation, primarily gamma rays, from winter thunderclouds and lightning in coastal areas of Japan. Starting in 2015, we have installed, in total, more than 15 units of ground-based detector system in Ishikawa Prefecture and Niigata Prefecture, and accumulated 551 days of observation time in four winter seasons from late 2015 to early 2019. In this period, our system recorded 51 gamma-ray radiation events from thundercloud and lightning. Highlights of science results obtained from this unprecedented amount of data include the discovery of photonuclear reaction in lightning which produces neutrons and positrons along with gamma rays, and deeper insights into the life cycle of a particle-acceleration and gamma-ray-emitting region in a thundercloud. The present paper reviews objective, methodology, and results of our experiment, with a stress on its instrumentation.
