CMS designed an high precision electromagnetic calorimeter, to be operated reliably
in the high radiation environment of the CERN Large Hadron Collider (LHC), inside
the 4 T magnetic field. Innovative solutions were developed to place the front-end
electronics within the detector with the advantage of minimizing external noise,
while reducing the number of optical links to send data...

The CMS Electromagnetic Calorimeter consists of roughly 76000 lead tungstate
crystals. Nearly 25000 Printed Circuit Boards of 5 different types and about 5500
Gigabit Optical Links are used to process the signals of the photo-detectors and to
send the resulting data to the off- detector electronics.
The integration of this electronics together with its cooling system, mechanical...

The Front-End (FE) boards are part of the on-detector electronics system
of the CMS electromagnetic calorimeter ECAL. Their numerical functionalities
and properties are tested by a dedicated test bench located at Laboratoire
Leprince-Ringuet, prior to the board integration in the CMS detector at CERN.
XFEST, acronym for eXtended Front-End System Test, is designed to perform
tests...

The CMS Preshower detector (ES) comprises ondetector and offdetector components of
the readout and control system, as well as the powering system and optical links.
The fast control system is largely built around the one originally conceived for
the CMS Tracker (FEC, DOH, CCU etc.) whilst the readout part profits from
developments made for the CMS ECAL (DCC, GOH, AD41240). There are two...

The AD41240 is a custom made 12-bit 40 MSPS, quad-channel, radiation tolerant analog-
to-digital converter for the front-end readout electronics of the CMS ECAL and
Preshower detectors. The A/D converter features a special digital circuitry to allow
automatic selection of gain ranges when it is used with a multi gain pre-amplifier.
This paper describes the design architecture of the A/D...
