Description
After successful LHC operation at the center-of-mass energy of 7 and 8
TeV in 2011 and 2012, plans are actively advancing for a series of
upgrades, culminating roughly 10 years from now in the high luminosity
LHC (HL-LHC) project, delivering of order five times the LHC nominal
instantaneous luminosity along with luminosity levelling. The final
goal is to extend the data set from about few hundred fb-1 expected
for LHC running to 3000 fb-1 by around 2030. Current planning in ATLAS
also has significant upgrades to the detector during the consolidation
of the LHC to reach full LHC energy and further upgrades to
accommodate running already beyond nominal luminosity this decade. The
challenge of coping with HL-LHC instantaneous and integrated
luminosity, along with the associated radiation levels, requires
further major changes to the ATLAS detector. The designs are
developing rapidly for an all-new inner-tracker, significant upgrades
in the calorimeter and muon systems, as well as improved triggers and
data acquisition. This presentation summarises the various
improvements to the ATLAS detector required to cope with the
anticipated evolution of the LHC instantaneous luminosity during this
decade and the next.
