European industry's potential capabilities for high power RF systems for the future ILC

The ILC baseline design identifies presently available technology that could in principle be used for its construction. But, to be viable, the associated cost must be greatly reduced and predicted performance, reliability and life improved. This applies equally to its RF systems. A brief view of European competence is presented in terms of new RF systems developments, available products and overall capability. Europe has a strong industrial base that can accept the challenges set by the ILC but it can only be engaged if the ILC is seen to be a good business prospect. Industry must be involved from an early stage, and its involvement based on risk sharing. Technical and commercial information should be readily available and there needs to be adequate funding.
