垂直腔面发射激光器（VCSEL）用于所有ATLAS检测器的光学传输。在一些但不是所有的子系统中使用的VCSEL的可靠性存在各种问题。本文简要回顾了VCSEL的设计和潜在的可靠性问题。故障分析（FA）中使用的一些技术解释与ATLAS操作过程中失败的设备的研究的例子。从不同的系统的故障率的估计和检测器操作的影响进行了讨论。试图诊断的问题的原因进行了说明。描述了受影响最严重的两个子系统的缓解策略。最后给出了VCSEL可靠性的一些结论和对ATLAS运行的展望。
Vertical Cavity Surface Emitting Lasers (VCSELs) are used for optical transmission for all ATLAS detectors. There have been various problems with the reliability of the VCSELs used in some but not all of the sub-systems. This paper briefly reviews the design of VCSELs and the potential reliability issues. Some of the techniques used in Failure Analysis (FA) are explained with examples from studies of devices that failed during ATLAS operation. Estimates of the failure rates from the different systems are given and the implications for detector operations are discussed. The attempts to diagnose the causes of the problems are described. The mitigation strategies for the two sub-systems most seriously affected are described. Finally some conclusions about VCSEL reliability and the outlook for ATLAS operation will be given.
