摘要:

Neutrinos Angra实验是一个基于水的切伦科夫探测器,位于巴西的Angra dos Reis核电站。该实验旨在探测核反应堆产生的电子反中微子,其主要目标是证明利用反中微子探测器监测反应堆活动的可行性。这项工作与国际原子能机构(IAEA)旨在识别适用于防扩散保障的潜在和新型技术的计划相一致。在地表运行面临高噪声率等挑战,因此需要开发非常灵敏但规模较小的探测器。这些条件使Angra实验成为开发应用以及获取新技术和分析方法专业知识的绝佳平台。该探测器采用掺杂钆的水基靶体,以增强其对反中微子的灵敏度。在这项工作中,我们描述了探测器的主要特征和电子学链路,包括前端和数据采集组件。我们详细介绍了数据采集策略以及用于信号处理和事例选择的方法。初步物理结果表明,该探测器能够通过探测反应堆电子反中微子诱发的逆贝塔衰变来可靠地监测反应堆运行。

英文摘要:

The Neutrinos Angra Experiment, a water-based Cherenkov detector, is located at the Angra dos Reis nuclear power plant in Brazil. Designed to detect electron antineutrinos produced in the nuclear reactor, the primary objective of the experiment is to demonstrate the feasibility of monitoring reactor activity using an antineutrino detector. This effort aligns with the International Atomic Energy Agency (IAEA) program to identify potential and novel technologies applicable to nonproliferation safeguards. Operating on the surface presents challenges such as high noise rates, necessitating the development of very sensitive, yet small-scale detectors. These conditions make the Angra experiment an excellent platform for both developing the application and gaining expertise in new technologies and analysis methods. The detector employs a water-based target doped with gadolinium to enhance its sensitivity to antineutrinos. In this work, we describe the main features of the detector and the electronics chain, including front-end and data acquisition components. We detail the data acquisition strategies and the methodologies applied for signal processing and event selection. Preliminary physics results suggest that the detector can reliably monitor reactor operations by detecting the inverse beta decay induced by electron antineutrinos from the reactor.
