自 80 年代初引入物理学界以来，电阻板室 (RPC) 作为带电粒子探测器的使用不断增加。单位面积成本低、时间分辨率好和易于操作是促成如此大规模采用的一些特性，并且使 RPC 对于一些不一定与物理相关的应用程序很有趣。我们构建了一个原型探测器来跟踪宇宙 μ 子，并利用通过估计多库仑散射角提供的信息来确定它们穿过的材料类型。模拟表明，该技术可用于在几分钟的时间内检查集装箱。我们构建的探测器由六个平面组成，每个平面在 50 cm × 50 cm 的区域内提供 X-Y 读数。我们采用的读出方案基于高能物理中使用的多路复用芯片，使我们能够使用有限数量的电子输出通道，同时仍然获得低于 1 毫米的空间分辨率。提供了检测器和对数据进行的分析的概述。
Following their introduction in the physics community in the early '80s the use of Resistive Plate Chambers (RPCs) as charged particles detectors has constantly increased. Low cost per unit area, good time resolution and easy of operation are some of the features that contributed to such large adoption and that make RPCs interesting for several applications not necessarily related to physics. We built a prototype detector to track cosmic muons and exploit the information provided by estimating the multiple coulomb scattering angle to determine the type of materials they traversed. Simulations show that the technique could be used to inspect a cargo container in a time of the order of minutes. The detector we built consists of six planes, each one providing X-Y readout over a 50 cm × 50 cm area. The readout scheme we adopted, based on multiplexing chips used in high energy physics, allowed us to use a limited amount of electronic output channels while still obtaining a spatial resolution lower than 1 mm. An overview of the detector and of the analysis performed on the data is provided.
