Project acronym: EUROTeV European Design Study Towards a Global TeV Linear Collider Proposal/Contract no.: 011899-DS Design study 1. Project Summary The three-year Design Study (DS) intends to contribute to the critical R&D for the proposed International Linear electron-positron Collider (ILC), operating at the centre-of-mass energy frontier of 500-1000 GeV. The DS will help lay the foundation for a future research facility of worldwide relevance. The Study addresses high-ranking critical issues identified by an international evaluation team – the ILC-TRC – and focuses on those issues that are largely independent of the acceleration technology. Within the same context, the DS will also support in part critical R&D for a possible multi-TeV facility (beyond the ILC). To reach the ambitious luminosity goals, ultra-low emittance beams have to be brought into collision. The Study specifically explores beam delivery schemes, damping rings and questions related to the metrology and stabilisation. The diagnostics required to monitor beams of a few nanometres is likewise addressed. A linear collider affords the possibility to collide two polarised beams; this Study addresses the efficient production of polarised positrons using undulators and the required polarimetry. The ILC will be realised as an international effort that will profit from the availability of new technologies for communication and remote operations. The Study will form part of the European contribution to the design of the ILC, and as such will complement similar efforts in Asia and the Americas. 2. Project website address: www.eurotev.org 3. Project Achievements: 1.1.2006 – 31.12.2006 The role of EUROTeV is key to the European scientific and organisational contribution to the ILC. In these key areas EUROTeV, often rather than the supporting institutes, stands for high-quality research and design that has attracted several young researchers and raised accelerator science to a significantly more popular topic in the European accelerator landscape. Since the inception of EUROTeV the ILC has moved via a so-called baseline design to a reference design report which will yield initial cost estimates for the entire machine. EUROTeV has contributed to several areas. Among the research areas, spanning from positron source via damping rings to the main linac, EUROTeV has contributed to all research topics. The beam transport calculations and diagnostics are of the most sophisticated available world-wide. The availability of various test beam facilities including the one at KEK in Japan makes it possible for EUROTeV members to participate in sophisticated and ILC relevant experiments. In all these institutions they are well respected and welcome. EUROTeV continues to lead the efforts for the Global Accelerator Network, the remote operation of accelerator components. The concept has meanwhile been extended to the detector network where test beam experiments have been remotely supported using the tools developed inside EUROTeV. 4.
