Abstract | To cope with the increased power requirements of future tracking detectors needed after the luminosity upgrade of the Large Hadron Collider (LHC) at CERN, novel powering schemes have been proposed. These include Serial Powering and powering via the DC-DC conversion technique. For the CMS pixel and strip tracker upgrades powering via DC-DC buck converters is foreseen. In this article, the current status of this development is described and measurements of important DC-DC converter characteristics such as efficiency and conductive and radiative noise emissions are presented. The mechanical and thermal integration into a future pixel detector is sketched and the results of system tests with CMS pixel modules are summarized. |
