报告摘要：
ATLAS is one of the four major experiments at the Large Hadron Collider (LHC), investigating a wide range of physics from collisions of two proton beams at high luminosity. The ATLAS trigger system must make irreversible, real-time decisions to select a tiny fraction of collision events within a short time. The Level-1 Trigger (L1) provides the first and largest step of selection. This talk gives a description of the Level-1 Calorimeter Trigger (L1Calo), which is a major component of L1, together with the ongoing upgrades to face the new challenges posed by the upcoming increase of LHC proton beam energy and luminosity.

报告人简介：Dr. Xiaoguang Yue graduated from the Department of Engineering Physics in Tsinghua University, where he obtained his Bachelor degree and PhD degree in Nuclear science and technology in 2011 and 2016, respectively.
He is currently working on the Phase-2 upgrade of ATLAS Level-1 Calorimeter Trigger as a postdoc at the Kirchhoff-Institute for Physics in Heidelberg University, Germany.
