Joint Study on Non-Accelerator Physics [LVD+LMD]

1. The Large Volume Detector （LVD） Experiment in the Gran Sasso地下实验室是一个multipurpose detector consisting of a large volume of liquid scintillator interleaved with limited streamer tubes in a Compact 3-dimensional geometry。LVD神经天文台的主要目的是寻找恒星碰撞。第一塔（每塔368吨）于1992年6月启用，第二塔也于1997年启用。当前中微子事件为500/（10分钟）和muon ones 40/（10分钟）。这是一个液体闪烁器的质量，它创造了世界上最大的超级新星中性观测台，也是基于液体闪烁器的两座塔。第三座塔在建筑下面。LVD小组介绍了LVD对低能量中性研究的能力，在这个初始阶段对恒星衰减信号的搜索的结果，以及对EAS-TOP （在表面）和LVD （深地下）探测器作为一个组合望远镜在宇宙射线主成分研究中操作的结果。The measured depth-angular distribution of muon intensities analyzed and the values of the upper limit on the ratio of prompt muon flux to that of pions have been obtained during 21804 hours of operation of the first LVD tower.2。大型大规模探测器（LMD）实验：热发光（TL）表格堆栈及其读取系统已开发用于检测超慢重粒子（例如， GUT单体）。TL-sheet stack （TLS）是一个包含双真空包的五张TL sheet和八张医用X射线电影的组成部分。1996年8月，LVD坦克上的25米D12 D1的TLS设置在较低的基础级无线电活动比Mont Blanc隧道。这些堆栈将被分析，以研究在Gran Sasso隧道墙中对超慢重粒子和α粒子的研究。

1. The Large Volume Detector (LVD) Experiment in the Gran Sasso underground Laboratory is a multipurpose detector consisting of a large volume of liquid scintillator interleaved with limited streamer tubes in a compact 3-dimensional geometry. A major purpose of the LVD neutrino observatory is to search for stellar collapses. The first tower (368 tons per one tower) was turn on in June 1992 and the second tower also in 1997. The current neutrino events are 500/(10 min. ) and muon ones 40/(10 min. ). This mass of liquid scintillator makes the two towers the largest super novae neutrino observatories in the world and the largest one based on liquid scintillator. The third tower is under construction. The LVD group presented the power of LVD to study low-energy neutrinos, the results of a search for stellar collapse signals in our Galaxy during this initial period and the first results of the combined measurements of the EAS-TOP (at the surface) and LVD (deep underground) detectors operating as a combined telescope in the study of the cosmic ray primary composition. The measured depth-angular distribution of muon intensities analyzed and the values of the upper limit on the ratio of prompt muon flux to that of pions have been obtained during 21804 hours of operation of the first LVD tower.2. The Large Massive Detector (LMD) Experiment : The thermoluminescent (TL) sheet stacks and its readout system have been developed for the detection of super-slow heavy particles (for example, GUT monopoles). The TL-Sheet stack (TLS) is consists of five TL sheets and eight medical X-ray films with double vacuum package. The TLS of the 25 mィイD12ィエD1 were set on LVD tanks in August 1996 at lower background sate of radio activities than Mont Blanc tunnel. These stack shall be analyzed for studying the search of super-slow heavy particles and alpha particle production by muon-nuclei interactions in Gran Sasso tunnel walls.
