Detector concepts at the international linear collider

The international linear collider, ILC, is a project for a 500 GeV linear electron positron collider, upgradable to 1 TeV, and also capable of running at energies below 500 GeV. The proposal is optimized for high luminosity and a clean collision environment. Such a machine is ideally suited to do precision studies of the electroweak breaking mechanism, study possible new physics scenarios, and search for new phenomena. It complements the LHC through precision and a well-known initial state. Experimentation at such a facility is a major challenge if the potential for precision given by the collider should be optimally utilized. In this article the state of the experimental proposals for the ILC is reviewed.
