The infrastructure for the electronics, such as cabling, mains power distribution,
low and high voltage power supplies, detector safety system, grounding and its
installation in the LHCb experimental cavern will be presented. In particular,
choices and compromises that have been made for power distribution, racks, cables and
cable ducts installation, grounding (EMC) and optical fiber link...

An overview of testing, time alignment, calibration and monitoring features in the
front-end electronics of LHCb is given. General features for this are defined and
examples are given of how this has been implemented in sub-detector specific front-
end electronics.

The LHCb Outer Tracker is composed of 55000 straw drift tubes.
The requirements for the OT electronics is the precise (1ns) drift
time measurement at 6% occupancy and 1MHz readout.
Charge signals form the straw detector are amplified, shaped and
discriminated by ATLAS ASDBLR chips.
Drift-times are determined and stored in the OTIS TDC and output to a GOL
serializer at L0...

In this paper the Front End electronics of the Scintillator Pad Detector (SPD) is
outlined. The SPD is a sub-system of the Calorimeter of the LHCb experiment designed
to discriminate between charged particles and neutrals for the first level trigger.
The complete system design is presented, describing its different functionalities
implemented through three different cards and two ASICs....

The document to be presented will describe the
electronic scheme and procedures of
a system implemented to test the Multi-Wired
Proportional Chambers after front-end
dressing for the LHCb Muon Detector and its results.
Given a dressed chamber, this
system is able to diagnose every channel based on
front-end output drivers’
response and noise rate versus threshold analysis, in...
