  1. 89. The CMS Low Voltage System
    Dr Sergei Lusin (Fermilab)
    06/09/2007, 11:00
    Oral
    The low voltage system for the on-detector electronics of the CMS Experiment comprises 12090 channels of low voltage power supplies, requiring 1182 KVA of power at the entrance to the CMS facility at CERN. The severe radiation environment inside the CMS experimental cavern combined with an ambient magnetic field reaching up to 1.3 kGauss at the detector periphery severely limit the...

  2. 82. The implementation of the power supply system of the CMS silicon strip tracker
    Dr Simone Paoletti (INFN sezione di Firenze)
    06/09/2007, 11:25
    Oral
    The power supply system of the silicon strip tracker of the CMS experiment provides HV bias and LV power to the 15 thousand silicon modules comprising the detector, arranged into 1944 "power groups" and 256 "control rings". Around 1200 power supply modules, disposed on 29 racks, operate in a "hostile" radiation and magnetic field environment, 10 m away from the beam crossing region. They...

  3. 114. Power distribution for SLHC trackers: challenges and solutions
    Marc Weber (Rutherford Appleton Laboratory)
    06/09/2007, 12:15
    Oral
    Current silicon detector systems power each detector module independently. For large-scale detectors like the LHC trackers, tens of thousands of cables are needed to power the front-end electronics. At the price of added material, the conventional independent powering is just manageable. For the SLHC trackers, with a five- to ten-fold increase in the number of electronic channels and increased...

  4. 75. Serial Powering of Silicon Sensors
    Dr Giulio Villani (Rutherford Appleton Laboratory)
    06/09/2007, 12:40
    Oral
    Serial powering of silicon sensors will reduce the volume of power cables, the passive material and power losses in cables of future silicon trackers by large factors. These benefits are crucial for silicon tracking at the Super-LHC. Noise performance and grounding and shielding of densely packaged modules are key challenges for serial powering. We extended our studies with six ATLAS...
