Roadmap for ILC Detector R&D Test Beams

Abstract

This document provides a roadmap for ILC detector test beam needs in the next 3 - 5 years. In this period, detector Letters of Intent are expected by fall 2008, the ILC Engineering Design Report to be submitted in ILC and its detectors in 2012. ILC detectors are required to have unprecedented precision to be able to elucidate new physics discoveries at TeV energies from the LHC and ILC machines, and to fully exploit experimental investifation at the electrweak unification energy scale. Ahieving this requires significant investment for detector test beam activities to complete the R&D needed, to test prototypes and (later) to qualify final detector system desgns, including integated system tess. This roadmap document describes the need for significant increases in resources for ILC test beam activities. It should be used by test beam facility managers and the worldwide ILC leadership to assure that the necessary resources and facilities are made available to meet the needs in time.
