0banalysis of Optical Layouts for the Phase 1 Upgrade of the Cern Large Hadron Collider Insertion Regions*
نویسندگان
چکیده
In the framework of the studies for the upgrade of the insertions of the CERN Large Hadron Collider, four optical layouts were proposed with the aim of reducing the beta-function at the collision point down to 25 cm. The different candidate layouts are presented. Results from the studies performed on mechanical and dynamic aperture are summarized, together with the evaluation of beam-beam effects. Particular emphasis is given to the comparison of the optics performance, which led to retain the most promising layouts for further development.

OPTICS IMPLICATIONS OF IMPLEMENTING Nb3Sn MAGNETS IN THE LHC PHASE I UPGRADE*
CERN has encouraged the US-LARP collaboration to participate in Phase I of the LHC luminosity upgrade by analyzing the benefits gained by using Nb3Sn technology to replace the functionality of select NbTi magnets that CERN is committed to construct. Early studies have shown that the much higher gradients (shorter magnetic lengths) and temperature margins (quench stability) of Nb3Sn magnets comp...
متن کاملترکش مزونهای سنگین در LHC
Large Hadron Collider (LHC) at CERN will provide excellent opportunity to study the production and decay of heavy mesons and baryons with high statistics. We aim at the heavy mesons in this work and calculate their fragmentation functions consistent with this machine and present their total fragmentation probabilities and average fragmentation parameters.
متن کاملThe ATLAS and CMS Plans for the LHC Luminosity Upgrade
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 envir...
متن کاملCERN 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 کاملSelected issues for the LHC luminosity upgrade
The Large Hadron Collider started its operations on September 10th 2008. In a realistic forecast it is supposed to demonstrate (or confute) the existence of the Higgs boson for the year 2014. After this date the physics of rare events will be explored more in details and an upgrade of the luminosity can make an important difference in the program of experiments at CERN. This thesis proposes sev...
