Timing Distribution at the LHC
This paper describes a unified approach to fast timing distribution at the LHC. The timing signals for each ring of the machine will be encoded and transmitted over optical links from the RF system to the PCR, where beam-synchronous messages will be added. High power laser transmitters will then broadcast the signals over singlemode optical fibres to the four LHC experiments, to the test beam a...
متن کاملSilicon Detectors for the Super LHC
The luminosity upgrade of the Large Hadron Collider (LHC) at CERN to the Super LHC (sLHC) will increase the radiation dose at the experiments by roughly an order of magnitude. The elevated radiation levels require the LHC experiments to upgrade their tracking systems with extremely radiation hard detectors, capable of withstanding about a 1-MeV neutron-equivalent (neq) fluence of 1016 per squar...

متن کاملTracking detectors for the LHC upgrade
The plans for an upgrade of the Large Hadron Collider LHC to the Super-LHC (sLHC) are reviewed with special consideration of the environment for the inner tracking system. A straw-man detector upgrade for ATLAS is presented, which is motivated by the varying radiation levels as a function of radius, and choices for detector geometries and technologies are discussed in the context of required si...
متن کاملSilicon Detectors at the LHC
The LHC detectors will have to function in a high radiation environment, fluences of up to 10 1 MeV neutron equivalents (neq)/cm 2 are expected over a 10 year period. They will have to cope with a 40 MHz collision rate and high particle multiplicities. In this environment, the detectors must provide efficient tracking and btagging capabilities. These requirements are met by the silicon systems ...
