The LHC started delivering collisions to the experiments at the end of 2009. It will ramp up in energy and luminosity, reaching the nominal design luminosity of 10^34 /cm^2/s after a few years. A series of improvements, dubbed the super-luminous-LHC (sLHC), are planned which will further increase the luminosity. This will lead to much bigger data sets for the experiments opening up new possibilities in particle physics. The ATLAS detector will need several improvements to cope with the higher instantaneous and integrated particle fluxes, and so be able to maximise the benefits of the sLHC.
I will outline the physics goals of the upgrade, discuss the LHC changes proposed giving some tentative time-scales, and go through the ATLAS plans for coping with luminosity up to 10^35 /cm^2/s. I will emphasise in particular the status of the all-new inner tracker that is planned for about 10 years from now.
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
