Abstract

The MURAVES experiment aims at the muographic imaging of the internal structure of the summit of Mt. Vesuvius, exploiting muons produced by cosmic rays. Though presently quiescent, the volcano carries a dramatic hazard in its highly populated surroundings. The challenging measurement of the rock density distribution in its summit by muography, in conjunction with data from other geophysical techniques, can help the modeling of possible eruptive dynamics. The MURAVES apparatus consists of an array of three independent and identical muon trackers, with a total sensitive area of 3 square meters. In each tracker, a sequence of 4 XY tracking planes made of plastic scintillators is complemented by a 60 cm thick lead wall inserted between the two downstream planes to improve rejection of background from low energy muons. The apparatus is currently acquiring data. Preliminary results from the analysis of a first data sample are presented. 1 ar X iv :2 20 2. 12 00 0v 1 [ ph ys ic s. in sde t] 2 4 Fe b 20 22
MURAVES实验:用介子射线照相法研究维苏威火山大锥
MURAVES实验的目的是利用宇宙射线产生的介子,对维苏威火山山顶的内部结构进行摄影成像。虽然目前处于平静状态,但这座火山在其人口密集的环境中带来了巨大的危险。用摄影法测量峰顶岩石密度分布具有挑战性,结合其他地球物理技术的数据,可以帮助建立可能的喷发动力学模型。MURAVES装置由三个独立且相同的μ子跟踪器阵列组成,总敏感面积为3平方米。在每个跟踪器中,由塑料闪烁体组成的4个XY跟踪平面序列,在两个下游平面之间插入60厘米厚的铅壁,以提高对低能μ子背景的抑制。该设备目前正在获取数据。本文给出了第一个数据样本分析的初步结果。[j] [X] [iv]: 22 [20][au:] [au:] [au:] [au:] [au:] [au:
