Commissioning and Performance of the ATLAS Liquid Argon Calorimeters
The ATLAS liquid argon (LAr) calorimeter system consists of an electromagnetic barrel calorimeter and two end-caps with electromagnetic, hadronic and forward calorimeters. The construction of the full calorimeter system is completed since mid-2004. The detector has been operated with LAr at nominal high voltage and fully equipped with readout electronics. Online software, monitoring tools and o...
متن کاملThe ATLAS Liquid Argon Calorimeters Read Out Drivers (ROD)
The Read Out Drivers (ROD), which are described here, are part of the electronics of the ATLAS Liquid Argon Calorimeters. A ROD module receives triggered data from 256 calorimeter cells. It calculates precise energy and timing of the calorimeters signals from discrete time samples. It also performs monitoring and formats data for the next element in the electronic chain. To assess the feasibili...
متن کاملEnergy-calibration of the Atlas Hadronic and Electromagnetic Liquid-argon Endcap Calorimeters
In 2002 the first combined beam test of the hadronic and electromagnetic liquidargon endcap calorimeters of the ATLAS experiment took place at the SPS test beam at CERN. A total of 15 million events from electrons, muons and pions in the energy range from 6 to 200GeV were recorded. The entire calibration chain, from digital filter weights, over calibration constants, to clustering and energy we...
متن کاملA high speed serializer ASIC for ATLAS Liquid Argon calorimeter upgrade
We have been developing a serializer application-specific integrated circuit (ASIC) based on a commercial 0.25-μm silicon-on-sapphire (SOS) CMOS technology for the ATLAS liquid argon calorimeter front-end electronics upgrade. The first prototype, a 5 Gbps 16:1 serializer has been designed, fabricated, and tested in lab environment and in 200 MeV proton beam. The test results indicate that the f...
متن کاملHVMUX, the High Voltage Multiplexing for the ATLAS Tracker Upgrade
The increased luminosity of the HL-LHC will require more channels in the upgraded ATLAS Tracker, as a result of the finer detector segmentation. Thus, an upgraded and more efficient HV biasing of the sensors will also be needed and is among the many technological challenges facing the ATLAS Tracker Upgrade. A number of approaches, including the sharing of the same HV line among several sensors ...
