Site Selection Criteria for European ILC Sites

This report describes a set of selection criteria for possible European sites, which are suitable for the construction of the International Linear Collider. The criteria were developed in the framework of the Global Design Effort activities. The footprint of the ILC are tunnels with a length of about 30 km in the first stage, a campus site in the center with the experimental hall, damping rings, beam delivery system and the injectors underground and equally distributed service halls at the surface. One European deep site near CERN at Geneva has been considered in the Reference Report of the International Linear Collider. Another possibility is a near to surface solution chosen for the European XFEL project in Hamburg, which is currently under construction and for the Linear Collider project TESLA. In addition, the Joint Institute for Nuclear Research JINR has also developed a shallow tunnel soft ground site in the neighborhood of Dubna in the Moscow region of the Russian Federation. Site selection criteria are needed for the future assessment of these and more European sites together with proposals from the other two regions the Americas and Asia. The criteria in this report are divided into several categories and some of them are explained in detail. An assessment matrix is developed and a sample is shown. It has to be pointed out that this report collects and describes only some technical criteria. Others may be added and political and socio-economic criteria are as important but these have to be discussed elsewhere.
