The ATLAS and CMS Plans for the LHC Luminosity Upgrade
نویسنده
چکیده
In January 2007 the CERN director general announced the plan for the staged upgrade of the LHC luminosity. The plan foresees a phase 1 upgrade reaching a peak luminosity of 3 × 10 cms followed by phase reaching up to 10 cms. We discuss the physics potential and the experimental challenges of an upgraded LHC running. The detector R&D needed to operate ATLAS and CMS in a very high radiation environment and the expected detector performance are also discussed.

CERN Upgrade Plans for the LHC and its Injectors
The primary goal of CERN and the Large Hadron Collider (LHC) community is to ensure that LHC is operated efficiently, that it achieves nominal performance in the shortest term, and that its performance steadily improves. Since several years the community has been discussing the directions for maximizing the physics reach of the LHC by upgrading the experiments, in particular ATLAS and CMS, the ...
متن کاملATLAS Upgrade for the Super LHC Meeting the challenges of a ten-fold increase in collisions
With the Large Hadron Collider (LHC) about to start collisions, plans are already advancing for an upgrade. In this super-LHC (sLHC) project, about ten times the LHC luminosity in some 8 years from now is aimed. Coping with the high instantaneous and integrated luminosity will require many changes to the ATLAS detector. The designs are developing rapidly for an all-new inner-tracker, big change...
متن کاملCMS Tracker Upgrade for HL-LHC: R&D Plans, Present Status and Perspectives
During the high luminosity phase of the LHC (HL-LHC), the machine is expected to deliver an instantaneous luminosity of 5× 10 cm−2s−1. A total of 3000 fb−1 of data is foreseen to be delivered, with the opening of new physics potential for the LHC experiments, but also new challenges from the point of view of both detector and electronics capabilities and radiation hardness. In order to maintain...
متن کاملATLAS IBL: a challenging first step for ATLAS Upgrade at the sLHC
With the LHC collecting data at 7 TeV, plans are already advancing for a series of upgrades leading eventually to about five times the LHC design luminosity some 10 years from now in the High Luminosity LHC (HL-LHC) project. The upgrades for ATLAS detector will be staged in preparation for HL-LHC. The first upgrade for the Pixel Detector will be the construction of a new pixel layer, which will...
متن کاملScenarios for the LHC Upgrade
The projected lifetime of the LHC low-beta quadrupoles, the evolution of the statistical error halving time, and the physics potential all call for an LHC luminosity upgrade by the middle of the coming decade. In the framework of the CARE-HHH network three principal scenarios have been developed for increasing the LHC peak luminosity by more than a factor of 10, to values above 10 cm−2s−1. All ...
