Abstract

The Jiangmen Underground Neutrino Observatory (JUNO) aims to determine the neutrino mass hierarchy by detecting antineutrinos from nuclear reactors using a large liquid scintillator volume. The detector employs approximately 20,000 20-inch photomultiplier tubes powered and read out by two electronics readout systems: underwater and above water. The back-end card (BEC) is a crucial component of the latter and links 7,000 underwater electronics boxes to the trigger system. 180 BECs have been installed and tested at the JUNO site, including self-tests and combined tests. This paper presents the current status of the BEC.

江门地下中微子观测站（JUNO）的目标是通过使用大型液体闪烁体来探测核反应堆中的反中微子，从而确定中微子的质量等级。该探测器采用约 20,000 个 20 英寸光电倍增管，由水下和水上两个电子读出系统供电和读出。后端卡（BEC）是后者的重要组成部分，它将 7,000 个水下电子箱与触发系统连接起来。在 JUNO 现场已安装和测试了 180 个 BEC，包括自测和联合测试。本文介绍了 BEC 的现状。
