宇宙射线 μ 子射线照相是一种对火山锥顶部 100 m 内密度变化进行成像的技术。在最佳检测条件下，μ介子射线照相的分辨率高达数十米，可以提供火山大厦顶部区域的图像，其分辨率比传统方法通常获得的分辨率要好得多。这种精确的测量有望为我们提供有关岩石密度分布异常的信息，例如密集的熔岩管道、低密度岩浆供应路径或上覆土壤深度压缩所带来的信息。 MU-RAY项目旨在建造μ介子望远镜并开发用于μ介子射线照相的新分析工具。要求望远镜能够在恶劣的环境下工作，具有低功耗、良好的角度和时间分辨率、大的活动面积和模块化等特点。该望远镜由两个面积为 2 x 2 平方米的 X-Y 平面组成，由三角形塑料闪烁体条制成。每个条带由与硅光电倍增器耦合的快速 WLS 光纤读取。读出电子器件基于 SPIROC 芯片。 (C) 2010 Elsevier B.V. 保留所有权利。
Cosmic-ray muon radiography is a technique for imaging the variation of density inside the top few 100 m of a volcanic cone. With resolutions up to 10s of meters in optimal detection conditions, muon radiography can provide images of the top region of a volcano edifice with a resolution that is considerably better than that typically achieved with conventional methods. Such precise measurements are expected to provide us with information on anomalies in the rock density distribution, like those expected from dense lava conduits, low density magma supply paths or the compression with depth of the overlying soil. The MU-RAY project aims at the construction of muon telescopes and the development of new analysis tools for muon radiography. The telescopes are required to be able to work in harsh environment and to have low power consumption, good angular and time resolutions, large active area and modularity. The telescope consists of two X-Y planes of 2 x 2 square meters area made by plastic scintillator strips of triangular shape. Each strip is read by a fast WLS fiber coupled to a silicon photomultiplier. The readout electronics is based on the SPIROC chip. (C) 2010 Elsevier B.V. All rights reserved.
