论文摘要

I阶段I触发读数电子升级的Atlas液体氩热量表的升级可在即将增加的大型强子对撞机亮度时在即将进行的操作过程中增强实验的物理范围。新系统安装在第二个大型强子对撞机长时间关闭中,将触发读数粒度提高到10倍及其精度和范围。因此,通过使用其他信息来提高过滤算法来提高触发水平的背景排斥,从而提高了电磁形状和辐射淋浴形状的拓扑歧视。本文介绍了新电子元素的最终设计,它们的定制电子设备,用于验证其正常功能的程序以及在此系统调试期间的性能。

The Phase-I trigger readout electronics upgrade of the ATLAS Liquid Argon calorimeters enhances the physics reach of the experiment during the upcoming operation at increasing Large Hadron Collider luminosities. The new system, installed during the second Large Hadron Collider Long Shutdown, increases the trigger readout granularity by up to a factor of ten as well as its precision and range. Consequently, the background rejection at trigger level is improved through enhanced filtering algorithms utilizing the additional information for topological discrimination of electromagnetic and hadronic shower shapes. This paper presents the final designs of the new electronic elements, their custom electronic devices, the procedures used to validate their proper functioning, and the performance achieved during the commissioning of this system.
