LHC Detector Upgrades

TL;DR

The paper discusses the upcoming upgrades needed for LHC detectors, especially the tracking systems of ATLAS and CMS, in preparation for the super LHC's increased luminosity and schedule.

Contribution

It highlights the necessity and planning for detector upgrades to handle the tenfold increase in luminosity at the super LHC.

Findings

Current detector designs are insufficient for future luminosity levels.

Significant R&D is required for new tracking system prototypes.

Upgrade timelines are aligned with the super LHC schedule.

Abstract

The LHC detectors are well into their construction phase. The LHC schedule shows first beam to ATLAS and CMS in 2007. Because the LHC accelerator has begun to plan for a ten fold increase in LHC design luminosity (the SLHC or super LHC) it is none too soon to begin to think about the upgrades which will be required of the present LHC detectors. In particular, the tracking systems of ATLAS and CMS will need to be completely rebuilt. Given the time needed to do the R&D, make prototypes, and construct the new detectors and given the accelerator schedule for the SLHC, work needs to begin rather soon.
