MPO Optical Fibers

http://lhcb-elec.web.cern.ch/lhcb-elec/cabling/MPOFiberTests/MpoMeasurementMain.htm

MPO Optical Fiber Cable Measurements. All the long distance multi-ribbon MPO optical fiber cables have been measured in power loss after installation in the cavern from the detector patch panel racks to the counting house racks. Those measures have been performed by the company who installed the cables and all results have been provided by them. All cables are identified by their serial numbers. The ribbons are then numbered from 1 to 8 and the fibers from 1 to 12. Link to the results.

ECS interface

http://lhcb-elec.web.cern.ch/lhcb-elec/html/ecs_interface.htm

The complete LHCb experiment ( magnet, power supplies, front-end, DAQ, etc.) must be under the control of the Experiment Control System (ECS). The ECS system will be responsible for the overall control of the experiment and the monitoring of its correct function. The ECS will be a highly hierarchical system with a large set of local controllers performing the control and monitoring of specific sub-systems. Radiation induced single event upsets. An important role of the ECS system is to continuously monit...

Synchronization

http://lhcb-elec.web.cern.ch/lhcb-elec/html/synchronisation.htm

Synchronization of front-end electronics. Phase alignment to bunch collisions. In some cases the clock phase alignment can be performed for a group of channels together. This though requires a careful matching of delays between the channels in the group ( flight time, detector delay, delay in analog front-end, cable delays, sampling delay, clock distribution on module or chip, etc.). As the synchronous L0 trigger decision also comes from this source. Synchronization to LHC bunch structure. And generate a...

Grounding

http://lhcb-elec.web.cern.ch/lhcb-elec/html/grounding.htm

Grounding of detectors and their electronics. Grounding of detectors and their associated electronics is a complicated and delicate problem in large experiments. The general aim in grounding is to prevent the pick up of noise in. Sensitive signal connections. Ground loops can potentially. Grounding, Shielding and Power Distribution in LHCb. Grounding network in LHCb. Electrical distribution network for the LHCb experiment. Mains power requirements for the LHCb experiment. Grounding in the counting house.
