基于厚GEM的WELL探测器的电击穿

Electrical breakdown in Thick-GEM based WELL detectors

Abhik Jash, Luca Moleri, Shikma Bressler

摘要:

气体检测器中放电的发生限制了其动态范围并降低了其性能。在为减轻放电效应而开发的不同方法中,发现在检测器组件中使用电阻材料非常有效。在这项工作中,我们提出了一个比较研究的结果,在厚GEM为基础的井型探测器的放电-有和没有电阻元件。我们提出了一种新的方法来测量放电的连续检测器配置,它允许演示,第一次,放电的发生也在电阻板的井检测器配置。它也为Raether极限提供了直接证据。

英文摘要:

The occurrence of electrical discharges in gas detectors restricts their dynamic range and degrades their performance. Among the different methods developed to mitigate discharge effects, the use of resistive materials in the detector assembly was found to be very effective. In this work, we present the results of a comparative study of electrical discharges in Thick-GEM-based WELL-type detectors - with and without resistive elements. We present a new method to measure discharges in the resistive-detector configurations; it allows demonstrating, for the first time, the occurrence of discharges also in the Resistive-Plate WELL detector configuration. It also provides direct evidence for the Raether limit.
