摘要

ATLAS实验旨在研究欧洲核子研究中心(CERN)大型强子对撞机(LHC)产生的质子-质子碰撞。液态氩取样量热计用于电子、光子和强子射流的识别和特性测量。自2010年首次对撞以来，量热计的运行几乎达到了最佳状态，在2012年7月宣布发现希格斯玻色子的过程中发挥了主导作用。本文将重点介绍高压供电系统的最新发展。这些努力使量热仪配备了创新的电源模块，能够暂时维持高电流负载而不会出现大的电压下降。

The Atlas liquid argon calorimeter at the CERN Large Hadron Collider: General performance and latest developments of the High Voltage system

The ATLAS experiment is designed to study the proton-proton collisions produced at the Large Hadron Collider (LHC) at CERN. Liquid argon sampling calorimeters are used for the identification and characteristics measurement of the electrons, photons and hadronic jets. Since the first collisions in 2010, the calorimeters operated almost optimally, playing a leading role in the discovery of the Higgs boson announced in July 2012. A special emphasis in this paper will be given on the latest developments of the high voltage power supply system. These efforts allowed to equip the calorimeters with innovative power supply modules able to temporarily sustain high current load without major voltage drop.
