BEACON计划旨在利用高海拔原型仪器探测超高能陶中微子产生的上行空气簇射射电辐射，通过定向波束成形触发抑制背景噪声，自2018年运行至今并已观测到疑似宇宙射线候选事件。
摘要：
宇宙中微子波束成形高架阵列（BEACON）是一台计划中的中微子望远镜，旨在探测由超高能陶中微子在地球内部相互作用产生的上行空气簇射的射电辐射。该探测机制可测量宇宙中微子的陶通量。我们在高海拔的Barcroft Field Station安装了一个8通道原型仪器，该仪器自2018年以来一直运行，由4副双极化天线组成，敏感频段为30-80 MHz，其信号通过定制数据采集系统（DAQ）进行滤波、放大、数字化并保存至磁盘。BEACON原型置于高海拔以最大化有效体积，并采用定向波束成形触发来提高在触发级对人为背景噪声的抑制。本文讨论了BEACON原型仪器的设计、建造和校准。我们还讨论了仪器观测到的射频环境，并对仪器观测到的事件类型进行了分类，包括一个可能的宇宙射线候选事件。
英文摘要：
The Beamforming Elevated Array for COsmic Neutrinos (BEACON) is a planned neutrino telescope designed to detect radio emission from upgoing air showers generated by ultrahigh energy tau neutrino interactions in the Earth. This detection mechanism provides a measurement of the tau flux of cosmic neutrinos. We have installed an 8-channel prototype instrument at high elevation at Barcroft Field Station, which has been running since 2018, and consists of 4 dual-polarized antennas sensitive between 30-80 MHz, whose signals are filtered, amplified, digitized, and saved to disk using a custom data acquisition system (DAQ). The BEACON prototype is at high elevation to maximize effective volume and uses a directional beamforming trigger to improve rejection of anthropogenic background noise at the trigger level. Here we discuss the design, construction, and calibration of the BEACON prototype instrument. We also discuss the radio frequency environment observed by the instrument, and categorize the types of events seen by the instrument, including a likely cosmic ray candidate event.
