ATLAS Upgrade for the sLHC: meeting the challenges of a five-fold increase in collision rate

Abstract

With the Large Hadron Collider (LHC) providing pp collisions data at √ s = 7 TeV, plans are already advancing for a series of upgrades leading eventually to about 5 × 10 34 cm −2 s −1 some ten years from now in the super-LHC (sLHC) project. The goal is to extend the dataset from about few hundreds fb −1 expected by 2020 to few thousands fb −1 by around 2030. High instantaneous and integrated luminosities are the challenge that will require many changes to the ATLAS detector. The designs are developing rapidly for a new tracking detector, significant changes in the calorimeter and muon systems, as well as improved triggers and data acquisition system. These proceedings summarise the environment expected at the sLHC and the status of the improvements to the ATLAS detector.

Power converters for future LHC experiments

“…The electronics which will instrument experiments during the high luminosity phase at the Large Hadron Collider (LHC), will require a new power distribution scheme compared to the one used today. Power architecture integrating point of load converters deployed at the very heart of the experimental setup has been proposed to face these new requirements [1][2][3][4][5][6].…”
