First Operational Experience and Performance Optimization of the ATLAS Magnet Cryogenic System / Delruelle, N (CERN) ; Barth, K (CERN) ; Dudarev, A (CERN) ; Passardi, G (CERN) ; Ten Kate, H H J (CERN)
The ATLAS magnet system, comprising a superconducting central solenoid and three superconducting toroids, has been successfully ramped up for the first time to the nominal operational current of 20.4 kA on 4th August 2008. Since then, new cryogenic operational challenges have been raised, like the smoothing of steady-state parameters, the enhancing of transient procedures to minimize thermal shocks on the magnet cold masses, the optimization of the complex cryogenic system in order to reduce the compressors electric consumption and finally how to avoid regular clogging of the shield refrigerator by water contamination. [...]

Drift Time Measurement in the ATLAS Liquid Argon Electromagnetic Calorimeter using Cosmic Muons / ATLAS Collaboration
The ionization signals in the liquid argon of the ATLAS electromagnetic calorimeter are studied in detail using cosmic muons. In particular, the drift time of the ionization electrons is measured and used to assess the intrinsic uniformity of the calorimeter gaps and estimate its impact on the constant term of the energy resolution. [...]

Readiness of the ATLAS Liquid Argon Calorimeter for LHC Collisions / ATLAS Collaboration
The ATLAS liquid argon calorimeter has been operating continuously since August 2006. At this time, only part of the calorimeter was readout, but since the beginning of 2008, all calorimeter cells have been connected to the ATLAS readout system in preparation for LHC collisions. [...]

Design Principles and Operational Results of the Cryogenic System for the ATLAS Liquid Argon Calorimeter / Fabre, C (CERN) ; Bremer, J (CERN) ; Chalifour, M (ITER, St. Paul Lez Durance) ; Gonidec, G (CERN) ; Passardi, Giorgio (CERN) ; Petit, P (LPSC, Grenoble) ; Pezzetti, M (CERN) ; Wicek, F (Orsay, LAL)
The ATLAS liquid argon calorimeter housed in three independent cryostats containing a total argon volume of about 78 m3 has been installed in the underground cavern. The three detectors have been cooled down following stringent temperature gradient limits and have been filled with liquid argon. [...]

First Cool-down and Test at 4.5 K of the ATLAS Superconducting Magnet System Assembled in the LHC Experimental Cavern / Passardi, Giorgio (CERN) ; Barth, K (CERN) ; Delruelle, N (CERN) ; Dudarev, A (CERN) ; Haug, F (CERN) ; Pavlov, O (CERN) ; Pezzetti, M (CERN) ; Pirotte, O (CERN) ; ten Kate, H H J (CERN) ; Baynham, D E (Rutherford) et al.
The four superconducting magnets (Barrel Toroid, two End-Cap Toroids and Central Solenoid) of the ATLAS detector have been tested individually at 4.5 K in the LHC underground experimental cavern. Subsequently, as foreseen in the final configuration, they have been cooled in parallel at 4.5 K and powering up to their nominal current (20.5 kA) is in progress, prior to the first LHC proton beam.

The Upgrade of the Control System for the CERN/NA62 Liquid Krypton Detector / Moraux, A (CERN) ; Bremer, J (CERN) ; Falaleev, V (CERN) ; Gonidec, A (CERN) ; Passardi, Giorgio (CERN) ; Pezzetti, M (CERN)
The NA62 experiment is a continuation of the CERN kaon research program and particularly of the NA48 experiment which was designed in the early 90’s to measure the direct CP violation with a very high precision. An important component of the experimental setup is an electromagnetic calorimeter filled with 9000 liters of high-purity liquid krypton at 120 K. [...]
