The electronics systems used to control, trigger, and acquire data from the four
experiments at LHC are, for the field of High Energy Physics, of unprecedented level
of complexity and sophistication.
In the case of CMS, users are gaining access to the counting room (USC55) at a late
stage with respect to the official LHC start-up date.
Measures taken to reduce the time required between...

The CMS electromagnetic calorimeter is composed of 76,000 PbWO_4 scintillating
crystals. The scintillating light is captured by photo-detectors, amplified and
digitized. The conversion is performed inside the detector volume and data are
transported through optical fibers to the off-detector electronics.
About 25,000 Printed Circuit Boards of 5 different types and...

We report the results of tests of 12800 Very Front End (VFE) readout cards for the
barrel of the CMS electromagnetic calorimeter. A thorough test sequence was applied
to each card including power-on test, burn-in and final detailed calibration. The
results show excellent uniformity of the VFE cards. For instance the analogue,
digital and buffer currents have average values of 1.59, 0.43...

The FEC-CCS is a custom made 9U VME64x card for the Off-Detector electronics of the
CMS detectors. Special effort has been invested in the design of the card in order
to make it compatible with the operational requirements of multiple CMS sub-
detectors namely the Tracker, the ECAL Crystals and ECAL Preshower, the PIXELs, the
RPCs and the TOTEM. This paper describes the design...
