  1. 31. Mobile Test Bench for the LHC Cryogenic Instrumentation Crate Commissioning
    Dr Rachel Avramidou (CERN and National Technical University of Athens)
    17/09/2008, 11:00
    Oral
    The installation of the Large Hadron Collider (LHC) at CERN is completed. The magnets are installed and the emphasis is shifted to the commissioning. This work focuses on the commissioning of the cryogenic instrumentation. The LHC is a two-ring superconducting accelerator and pp collider of 27 km circumference.. The dipoles will operate at 8.3 T, cooled by superfluid helium at 1.9 K. The...

  2. 33. The Radiation Tolerant Electronics for the LHC Cryogenic Controls: Basic Design and First Operational Experience
    Dr Juan Casas-Cubillos (CERN)
    17/09/2008, 11:25
    Oral
    The LHC optics is based in the extensive use of superconducting magnets covering 23 km inside the tunnel. The associated cryogenic system for keeping the magnets in nominal conditions is hence distributed all around the 27 km LHC tunnel and the cryogenic instrumentation submitted to the LHC radiation environment is composed of close to 18’000 sensors and actuators. Radiation Tolerant (RadTol)...

  3. 84. Results from the Commissioning of the ATLAS Pixel Detector
    Lucia Masetti (Institut fur Physik)
    17/09/2008, 11:50
    Oral
    The ATLAS Pixel Detector is the innermost detector of the ATLAS experiment at the Large Hadron Collider at CERN. Approximately 80 M electronic channels of the detector, made of silicon, allow to detect particle tracks and secondary vertices with very high precision. After connection of cooling and services and verification of their operation the ATLAS Pixel Detector is now in the...

  4. 131. Design, production and first operation of the ALICE Silicon Pixel Detector system
    Dr Alex Kluge (CERN)
    17/09/2008, 12:15
    Oral
    The ALICE Silicon Pixel Detector (SPD) constitutes the two innermost barrel layers of the ALICE experiment. The SPD is the detector closest to the interaction point, mounted around the beam pipe at r=3.9 cm and 7.6 cm, respectively. In order to reduce multiple scattering the material budget per layer in the active region has been limited to ≈1% X0. It consists of 120 hybrid silicon pixel...

  5. 29. Installation, Commissioning and Performance of the CMS Electromagnetic Calorimeter Electronics
    Nicolo Cartiglia (Univ. + INFN)
    17/09/2008, 12:40
    Oral
    This talk reviews the CMS high resolution electromagnetic calorimeter (ECAL) on- and off-detector electronics and its commissioning within CMS in-situ. In particular it presents results on electronics noise, monitoring, dead channels and performance , together with the experience gained during installation. The talk will also include results from the first months of ECAL operation during...

  6. 137. Installation and Commissioning of the ATLAS LAr Read-Out Electronics
    Guy Perrot (Laboratoire d'Annecy-le-Vieux de Physique des Particules (LAPP))
    17/09/2008, 13:05
    Oral
    The cryostats of the ATLAS LAr calorimeter system are installed in the ATLAS cavern since several years. Following this, an effort to install and commission the front end read-out electronics (infrastructure, crates, boards) has been ongoing and is finished now, in time for the cavern closure. Following cautious procedures and with continuous testing-campaigns of the electronics at each...
