  1. 84. System Tests of the ATLAS Pixel Detector
    Dr Kendall Reeves (Uni. Wuppertal)
    15/09/2005, 11:00
    Oral
    The innermost part of the ATLAS (A Toroidal LHC ApparatuS ) experiment at the LHC (Large Hadron Collider) will be a pixel detector, which is presently under construction. Once installed into the experimental area, access will be extremely limited. To ensure that the integrated detector assembly operates as expected, a fraction of the detector which includes the power supplies and...

  2. 25. Performance of CMS pixel detector barrel modules
    Mr Christoph Hoermann (University of Zuerich/ Paul Scherrer Institut)
    15/09/2005, 11:25
    Oral
    The central part of the CMS pixel detector will consist of about 800 modules, which are mounted on three concentric barrel layers. The radii of the layers are 4cm, 7cm and 11cm. The modules cover an area of 66.5mm * 18.5mm and have 66560 pixels. The 16 Read Out Chips are connected to the sensor by bump bonds. The performance of the prototype modules has been evaluated in detail in...

  3. 73. Pixel Multichip Module Development at Fermilab
    Mr Marcos Turqueti (Fermilab)
    15/09/2005, 11:50
    Oral
    The efforts of the Pixel Detector R&D group at Fermilab have been concentrated on meeting the requirements of the pixel detector for the BTeV experiment. In BTeV, the pixel detector would be located close to the beam, and all collected data would be read out for use in the lowest level trigger for track and vertex reconstruction every beam crossing. We present the results of the...

  4. 17. Concept, realization and characterization of serially powered pixel modules
    Mr Duc Bao Ta (Rheinische Friedrich-Wilhelms Universität Bonn)
    15/09/2005, 12:15
    Oral
    We demonstrate here for the example of the large scale pixel detector of ATLAS that Serial Powering of pixel modules is a viable alternative powering scheme that have been devised and implemented for the modules using dedicated on-chip voltage regulators and modified flex hybrid circuits. The equivalent of a pixel ladder consisting of six serially powered pixel modules with about 0.3...

  5. 88. Study of serial powering of ATLAS silicon strip sensors
    Dr Marc Weber (Rutherford Appleton Laboratory)
    15/09/2005, 12:40
    Oral
    Serial powering of silicon detectors can dramatically reduce the number of power cables. This will relax space constraints, reduce material, and minimize power losses in cables. A study of the power efficiency of a serial powering scheme for silicon strip detector modules is performed. Numerical results are presented as a function of the number of modules, supply voltage, and cable...
