Towards experimentation at a Future Linear Collider

Abstract : This document highlights aspects of the research program for a future linear electron positron collider enabling precision physics at the TeV scale where phenomena reaching beyond the Standard Model of particle physics are expected to appear. The most advanced proposal for such a machine is the International Linear Collider (ILC) which is designed for centre-of-mass energies between 90 GeV and 1 TeV. Earlier precision measurements suggest the existence of the Higgs boson with a mass of around 120 GeV. Employing nominal parameters on beam characteristics and luminosity, the ILC promises to arrive at a precision of 2-3% on the Higgs-strahlung cross section and of around 30 MeV on the mass of the Higgs boson. The detectors to be operated at the ILC will feature highly granular calorimeters. This new type of calorimeters is the main tool to achieve the envisaged jet energy resolution of 30%/\sqrt{E}. The electromagnetic calorimeter will use tungsten as absorber material and it is currently favoured to employ silicon diodes as the active material. The document describes details of the successful R&D program for this calorimeter in terms of mechanics and the development of the read out electronics which will be interleaved with the calorimeter layers. The status of the development of the silicon wafers is outlined as well. The results obtained in beam test campaigns with a first prototype confirm the parameters employed in the studies for the Letter of Intent published in 2009 by the detector concept group ILD.
