Abstract

The demand for a large number of readout channels has been a limiting factor for the application of micropattern gaseous detectors (MPGDs) in achieving higher spatial resolution and larger detection areas. This challenge is further compounded by issues related to system integration, power consumption, and cost efficiency. To address these challenges, this study proposes two novel multiplexing methods based on Eulerian circuits. Mathematical calculations indicate that with n electronic channels, up to

$n \times (n-1)/2 - (n - 2)/2 + 1$

detector channels can be read out, where n is even. Three types of multiplexing circuits were designed, implemented, and tested in combination with micromesh gaseous structure (Micromegas) detectors. Experimental results demonstrate that for a multiplexing circuit with a factor of 8, the spatial resolution remains comparable to the direct readout method, while achieving a detection efficiency exceeding 94%. For a circuit with a multiplexing factor of 16, although the spatial resolution shows a slight degradation, the detection efficiency remains above 93.6%. These results demonstrate that the proposed multiplexing methods can significantly reduce the number of readout channels while maintaining an acceptable level of spatial resolution and detection efficiency. These findings highlight the potential of the proposed multiplexing techniques for applications in fields requiring high-resolution and cost-effective detector systems, such as cosmic-ray muon imaging.

一种用于微图样气体探测器的高压缩比信道复用方法

对大量读出通道的需求一直是微模式气体探测器（MPGDs）在实现更高空间分辨率和更大探测区域方面应用的限制因素。与系统集成、功耗和成本效率相关的问题进一步加剧了这一挑战。为了解决这些挑战，本研究提出了两种基于欧拉电路的新型多路复用方法。数学计算表明，使用n个电子通道，最多可读出$n \次(n-1)/2 - (n- 2)/2 + 1$检测器通道，其中n为偶数。结合微孔气体结构（Micromegas）探测器，设计、实现并测试了三种类型的多路复用电路。实验结果表明，对于倍数为8的复用电路，其空间分辨率与直接读出方法相当，同时检测效率超过94%。对于复用系数为16的电路，虽然空间分辨率略有下降，但检测效率仍保持在93.6%以上。这些结果表明，所提出的多路复用方法可以显著减少读出通道的数量，同时保持可接受的空间分辨率和检测效率水平。这些发现突出了所提出的多路复用技术在需要高分辨率和低成本探测器系统的领域中的应用潜力，例如宇宙射线介子成像。

期刊介绍： The IEEE Transactions on Nuclear Science is a publication of the IEEE Nuclear and Plasma Sciences Society. It is viewed as the primary source of technical information in many of the areas it covers. As judged by JCR impact factor, TNS consistently ranks in the top five journals in the category of Nuclear Science & Technology. It has one of the higher immediacy indices, indicating that the information it publishes is viewed as timely, and has a relatively long citation half-life, indicating that the published information also is viewed as valuable for a number of years. The IEEE Transactions on Nuclear Science is published bimonthly. Its scope includes all aspects of the theory and application of nuclear science and engineering. It focuses on instrumentation for the detection and measurement of ionizing radiation; particle accelerators and their controls; nuclear medicine and its application; effects of radiation on materials, components, and systems; reactor instrumentation and controls; and measurement of radiation in space.
