Abstract

These days, while the landscape of discoveries at LHC has yet to be unveiled, planning for upgrades twenty years or more in advance towards a possible experimental scenario, might sound very imaginative and ambitious. Nevertheless, as plans are being worked out for the High Luminosity LHC upgrade, it is possible to plan keeping the ATLAS and CMS detectors operational for the following High Energy phase. The natural and radiation-induced aging of some components, calorimeters especially, needs to be carefully addressed. Even planning for a very new detector might not be unreasonable.
