  2. CDR proposal – Cost estimate Coldmass cost estimate (per magnet). This cost estimate does not include the auxiliary infrastructure needed for superconducting magnets such as cryo-refrigeration plants, cryostats, power supplies, and current leads Nb 3 Sn, kCHF Nb-Ti, kCHF Comparison - Stable operations - Proven technology, ductile high margin to critical current material but current design and high temperature margin. requires operation at 95% on - More options for cryogenics the load line operation at 4.5 K. - Shorter magnets can produce same field amplitude Tooling 11.6 9.1 Components 321.1 130.2 Design Office 2.1 2.1 Manpower Manufacturing 97.5 75.1 Total Cost 432.2 216.5 2

  3. Nb-Ti Baseline Design • Wiggler with similar parameters as CLIC damping-ring wiggler can be used for beamline at ANKA. • Conceptual design done within CERN-KIT collaboration, technical design within CERN-KIT-BINP collaboration until end of 2011. • Installation until end of 2012 (latest). Open Issues: • What is the contribution of CERN, KIT, and BINP? • Vacuum, cryogenics, magnet protection, measurement, current leads, interconnection issues must be addressed and coordinated. (Establishment of a project structure?) 3

  4. Nb 3 Sn Advanced Design • In parallel with the Nb-Ti baseline design we will advance with the Nb 3 Sn design, first tests have shown the feasibility of Nb 3 Sn. • Nb 3 Sn technology for wiggler is less demanding than for accelerator magnets (inner triplets, LHeC, 11 T dipole projects) because of modular geometry, force distribution, and short unit lengths of wire. Open issues: • Nb 3 Sn short model testing (unavailability of Block 4 until Summer 1011). • For a first full prototype around 20 km strand are needed (approx. 200 kCHF). Strand procurement has a long lead time; when to start with the procurement process? • Nb 3 Sn prototype design is planned to be finished by the end of 2011, but production delay due to LHC consolidation in 2012. 4
