摘要微阻阱（μ RWELL）探测器是一种具有单阱放大级的新型火花保护微模式气体探测器（MPGD）。通过在读出板（μ RWELL PCB）上集成阱型放大结构和电阻电极，μ RWELL探测器仅由阴极PCB和μ RWELL PCB组成，从而使得组装过程非常简单，无需任何胶合、拉伸、拉伸或其他MPGD组装中常见的其他复杂操作。μ RWELL探测器的一个关键组件是电阻电极，它负责火花抑制，从而保持探测器的稳定运行。本文介绍了一种10 cm× 10 cm μ RWELL探测器，它具有两层相互垂直的读出带。它的电阻电极是用磁控溅射技术镀上一层薄的类金刚石膜。利用X射线系统地研究了μ RWELL探测器的增益性能和速率性能，并利用测试光束测量了其探测效率和空间分辨率。该探测器在两个维度上的空间分辨率均优于70 μ m，探测效率高于90%。
Abstract The Micro-Resistive WELL (μ RWELL) detector is a novel spark-protected Micro-Pattern Gaseous Detector (MPGD) with a single well-type amplification stage. By integrating a well-type amplification structure with a resistive electrode on a readout board (μ RWELL PCB), the μ RWELL detector is only composed of a cathode PCB and a μ RWELL PCB, resulting in a very simple assembling process without any gluing, stretching, tensioning or other complicated operation commonly practiced in assemblies of other MPGDs. A critical component of the μ RWELL detector is the resistive electrode that is responsible for spark suppression, and hence maintains stable operation of the detector. In this paper, we present a 10 cm× 10 cm μ RWELL detector with two layers readout strips perpendicular to each other. Its resistive electrode is made of a thin coating of Diamond-Like Carbon by magnetron sputtering technique. The gain performance and rate capability of this μ RWELL detector were systematically studied with X-rays, and its detection efficiency and spatial resolution were measured with a test beam. The detector can achieve a spatial resolution better than 70 μ m in both dimensions while the detection efficiency is higher than 90%.
