论文摘要
在本文中，我们为Legend-200实验的液体氩仪仪提供了详细的技术描述，并在意大利nazionali nazionali del Gran sasso中寻找了非常罕见的，假设的中性s $β$衰减过程。该设计源于需要读取出出色的单光子分辨率的液体氩气闪光灯的硅光塑料响应。必须将FE电子设备放置在远离探测器的地方，以满足实验的无线电限制。该约束代表了高信噪比的挑战。我们解决如何以稳定的方式实现这一目标。该系统于2021年7月安装，并已与Legend-200的其他地区进行了委托，证明我们可以达到250 $ $ $ V峰峰的总体电噪声水平非常低。
In this paper we provide a detailed technical description of the Front-End (FE) electronics for the liquid Argon instrumentation of the LEGEND-200 experiment, searching for the very rare, hypothetical neutrinoless double $β$ decay process at the Italian Laboratori Nazionali del Gran Sasso. The design stems from the need to read out the silicon photo-multiplier response to the scintillation light in the liquid Argon with excellent single-photon resolution. The FE electronics is required to be placed far from the detectors to meet the experiment's radio-purity constraints. This constraint represents a challenge for a high signal-to-noise ratio. We address how this could be achieved in a stable way. The system was installed in July 2021 and has been commissioned with the rest of LEGEND-200, proving we could attain a very low overall level of electrical noise of 250 $μ$V peak-to-peak.
