摘要

台山反中微子观测站(TAO)是江门地下中微子观测站(JUNO)的卫星实验。它的主要目的是通过探测 v̅e + p⟶ e + + n 反应中产生的光来精确测量反应堆的反中微子能谱,为 JUNO 提供参考。通过使用最先进的硅光电倍增管(SiPM)对球面(∼10 m2)进行检测,每 MeV 大约可以检测到 4,500 个光电子,从而实现了亚百分之一的能量分辨率。在这项工作中,我们介绍了基于低噪声、高速前端板(FEB)的读出电子装置的实施架构,该前端板连接到 50×50 平方毫米的滨松硅光电倍增管(SiPM Hamamatsu)瓦上,由 32 个各为 12×6 平方毫米的硅光电倍增管元件组成,分为两个独立的输出通道。总计 4,024 个 FEB 将通过八个定制法兰供电,这些法兰的功率约为 1.5 千瓦。在同一法兰上,8048 根输出信号电缆被分配和路由到基于 Virtex Ultrascale FPGA 的前端控制器 (FEC),FEC 最多可管理 8 个 16 通道 ADC,单个 FEC 上共有 128 个通道,最大采样率为 250 MHz,分辨率为 12 位。专用的触发和数据采集系统将过滤和记录发生的事件,剔除暗计数事件。我们报告了批量生产前 FEB 的鉴定结果,这些结果遵循了为实验定义的主要性能指标,显示单个光电子分辨率优于 13%,动态范围高达 250 个光电子。

SiPM and readout electronics for the JUNO-TAO Central Detector
The Taishan Antineutrino Observatory (TAO) is a satellite experiment of the Jiangmen Underground Neutrino Observatory (JUNO). TAO consists of a spherical ton-level Gadolinium-doped Liquid Scintillator detector and its main purpose is the precise measurement of the reactor antineutrino spectrum by detection of light produced in v̅e + p⟶ e + + n reaction, as a reference for JUNO. About 4,500 photoelectrons per MeV could be detected by instrumenting the sphere surface (∼10 m2) with state-of-the-art Silicon PhotoMultipliers (SiPMs), resulting in a sub-percent energy resolution. In this work we present the implemented architecture of the readout electronics based on low-noise, high-speed Front-End Boards (FEBs) connected to a 50×50 mm2 SiPM Hamamatsu tile, composed by 32 SiPM elements of 12×6 mm2 each, divided into two independent output channels. The overall 4,024 FEBs will be supplied through eight custom flanges that have to bring in about 1.5 kW. On the same flanges the 8,048 output signal cables are distributed and routed to the Front-End Controllers (FECs), based on Virtex Ultrascale FPGAs, able to manage up to eight 16-channel ADCs, for a total of 128 channels on a single FEC, with a maximum sampling rate of 250 MHz with 12-bit resolution. A dedicated trigger and data-acquisition system will filter and record occurring events, rejecting dark count events. We report the results of the characterization for the pre-production FEBs batch, following the main figures of merit defined for the experiment, showing single photoelectron resolution better than 13% and dynamic range up to 250 photoelectrons.
