Abstract

The Multigap Resistive Plate Chamber (MRPC), widely used in high-energy particle and nuclear physics experiments due to its excellent time resolution and efficiency, faces aging challenges under the higher radiation environment expected in future high flux experiments. This paper investigates the morphological and elemental changes in aged MRPC using Scanning Electron Microscope (SEM) and Atomic Force Microscope (AFM), revealing a clear connection between aging and fishing line spacer structure. Possible aging mechanisms are further discussed with electric field simulations. To address the aging issues associated with fishing line spacers, we developed a novel MRPC prototype that features thermal bonding spacers. Comparative tests under X-rays demonstrate that the prototype with thermal bonding spacers exhibits significantly enhanced anti-aging capabilities compared to conventional fishing line spacer MRPCs.

研究了MRPC的老化问题，研制了热粘合垫片抗老化的MRPC

多间隙电阻板腔（MRPC）以其优异的时间分辨率和效率广泛应用于高能粒子和核物理实验中，但在未来高通量实验中更高的辐射环境下面临老化挑战。利用扫描电镜（SEM）和原子力显微镜（AFM）研究了老化后MRPC的形态和元素变化，揭示了老化与钓鱼线间隔结构之间的明确联系。通过电场模拟进一步讨论了可能的老化机制。为了解决与钓鱼线隔离器相关的老化问题，我们开发了一种新型MRPC原型，该原型具有热粘合隔离器。x射线对比测试表明，与传统的钓鱼线隔离剂mrpc相比，热粘合隔离剂的原型具有显著增强的抗老化能力。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
