ATLAS Upgrade for the HL-LHC: meeting the challenges of a five-fold
increase in collision rate    [PDF]

Peter Vankov

With the LHC successfully collecting data at 7 TeV, plans are actively
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. 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, significant changes in the calorimeter
and muon systems, as well as improved triggers. This article summarizes the
environment expected at the HL-LHC and the status of various improvements to
the ATLAS detector.
