Description
In this seminar, I will review the properties of the calorimeters used in the generalpurpose
LHC experiments, and the challenges that these instruments are likely to encounter
during LHC operation. I will also look into the future, and discuss the demands
on calorimeter performance in future experiments at the ILC/CLIC. Whereas the design
of the ATLAS and CMS calorimeter systems was driven by the desire to measure
electromagnetic showers with high precision, the detectors at a future linear e+e- collider
will be shaped by the need to measure the four-vectors of fragmenting quarks and
gluons much more precisely than in previous generations of experiments.. I will discuss
in some detail the (underlying reasons for the) obstacles one faces in trying to meet
these demands. The difficulties encountered in calibrating a longitudinally segmented
calorimeter system will be emphasized in this discussion.
I will also describe current R&D efforts that are being carried out in this context, and
present the latest results of these projects.
