摘要:

正在为ATLAS液氩量热计第二阶段升级开发一个光学连接系统。光链路系统负责将来自1524个前端板(FEB)的超过18.2万个探测器通道的数据通过每个FEB的26根光纤传输到计数室,传输距离超过150米,并将时钟、束流交叉复位信号和慢速控制/监测信号带回FEB。光链路系统基于低功耗千兆位收发器(lpGBT)和多功能光收发器(VTRx+)模块,这两个模块都是为高亮度LHC升级而开发的。设计了评估板,对光链路系统的主要功能进行了评估。文中介绍了光链路系统的设计和主要功能的评价。

英文摘要:

An optical link system is being developed for the ATLAS Liquid Argon Calorimeter Phase-II upgrade. The optical link system is responsible for transmit the data of over 182 thousand detector channels from 1524 Front-End Boards (FEBs) through 26 optical fibers per FEB over 150 meters to the counting room and brings clocks, bunch crossing reset signals and slow control/monitoring signals back to the FEBs. The optical link system is based on the Low-Power GigaBit Transceivers (lpGBTs) and the Versatile optical Transceiver (VTRx+) modules, which both are being developed for the High-Luminosity LHC upgrade. An evaluation board is designed and the major functions of the optical link system are being evaluated. The design of the optical link system and the evaluation of major functions are presented in the paper.
