Abstract
| The upgrade of the CMS silicon tracker for the Super-LHC presents many
challenges. The distribution of power to the tracker is considered
particularly difficult, as the tracker power consumption is expected to be
similar to or higher than today, while the operating voltage will decrease
and power cables cannot be exchanged or added. The CMS tracker has adopted
parallel powering with DC-DC conversion as the baseline solution to the
powering
problem. In this paper, experimental studies of such a DC-DC conversion
powering scheme are presented, including system test measurements with custom
DC-DC converters and current strip tracker structures, studies of the detector
susceptibility to conductive noise, and simulations of the effect of novel
powering schemes on the strip tracker material budget. |
