Abstract

Operating on a surface with high noise rates and requiring susceptible, yet small-scale detectors, the Neutrinos-Angra detector is an excellent platform for technological development and expertise in new detection methods. This report details the primary features of the detector, the electronics involved, and preliminary physics results from the operational phase, particularly the ON-OFF analysis comparing the signals with the reactor in operation (ON) and during the maintenance shut-down (OFF), demonstrating the detector's capability to monitor reactor activity. Additionally, we will briefly discuss the prospects of using a cryogenic calorimeter to detect neutrinos via Coherent Elastic Neutrino-Nucleus Scattering (CEvNS), highlighting potential advancements in neutrino detection technology. Looking ahead, the project promises to play a crucial role in the integration of Latin American scientists and engineers into global scientific collaborations, significantly contributing to the LASF4RI and the broader HECAP strategic framework.

从保障应用到基础物理学：ν-Angra实验在反应堆中微子探测方面取得的进展

中微子-Angra 探测器在高噪声率的表面上运行，需要易受影响的小规模探测器，因此它是开发新探测方法技术和专门知识的绝佳平台。本报告详细介绍了探测器的主要特点、相关电子设备以及运行阶段的初步物理结果，特别是对反应堆运行（ON）和维护关闭（OFF）时的信号进行的ON-OFF分析比较，展示了探测器监测反应堆活动的能力。此外，我们还将简要讨论利用低温量热计通过相干弹性中微核散射（CEvNS）探测中微子的前景，强调中微子探测技术的潜在进步。展望未来，该项目有望在拉美科学家和工程师融入全球科学合作方面发挥关键作用，为 LASF4RI 和更广泛的 HECAP 战略框架做出重大贡献。
