摘要:

当面临具有挑战性的物流和受限环境时,使用常规成像技术变得有问题。特别是,这种情况在考古和采矿勘探以及核废料定性领域并不罕见。对于这些应用,即使使用muography也是复杂的,因为检测器必须部署在具有有限的仪器空间的困难区域中,例如,狭窄的隧道为了解决这一限制,我们已经开发了一种便携式μ介子探测器(muoscope)的基础上玻璃电阻板室(RPC)的有效面积为16 $\times$ 16厘米$^{2}$。在开发我们的第一个原型时考虑的具体设计目标是便携性,鲁棒性,自主性,多功能性,安全性和低成本。为了帮助进一步提高我们的设计目标,我们目前正在研究将敏感单元从旧原型中的条带切换到新原型中的像素的可能性。然而,为了执行高分辨率muography,每层的读出单元数量也需要显着增加,导致muoscope的整体成本和功耗增加。为了缓解这些问题,我们正在开发一种新的2D多路复用算法,用于用单个电子通道读出多个像素。本文对探测器的发展进行了综述,主要介绍了探测器的设计目标和探测器技术的选择。此外,我们提出的新原型的预期变化的细节,以及基于一般原则的模拟2D多路复用研究。

英文摘要:

The use of conventional imaging techniques becomes problematic when faced with challenging logistics and confined environments. In particular, such scenarios are not unusual in the field of archaeological and mining explorations as well as for nuclear waste characterization. For these applications, even the use of muography is complicated since the detectors have to be deployed in difficult areas with limited room for instrumentation, e.g., narrow tunnels. To address this limitation, we have developed a portable muon detector (muoscope) based on glass Resistive Plate Chambers (RPC) with an active area of 16 $\times$ 16 cm$^{2}$. The specific design goals taken into consideration while developing our first prototype are portability, robustness, autonomy, versatility, safety and low cost. To help further improve our design goals, we are currently studying the possibility to switch the sensitive units from strips in the old prototype to pixels for the new one However, for performing high resolution muography, the number of readout units per layer will also need to increase significantly, leading to increase in the overall cost and power consumption of the muoscope. To mitigate these issues, we are developing a novel 2D multiplexing algorithm for reading out several pixels with a single electronic channel. In this article, we give an overview of the detector development, focusing mainly on the design goals and the choice of detector technology. Furthermore, we present the details of the expected changes in the new prototype as well as a simulated 2D multiplexing study based on general principles.
