CDR proposal – Cost estimate

Nb3Sn, kCHF Nb-Ti, kCHF Comparison

  • Stable operations

high margin to critical current and high temperature margin.

  • More options for cryogenics
  • peration at 4.5 K.
  • Shorter magnets can produce

same field amplitude

  • Proven technology, ductile

material but current design requires operation at 95% on the load line

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-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?)

Nb3Sn Advanced Design

  • In parallel with the Nb-Ti baseline design we will advance with the

Nb3Sn design, first tests have shown the feasibility of Nb3Sn.

  • Nb3Sn 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:

  • Nb3Sn 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?

  • Nb3Sn prototype design is planned to be finished by the end of

2011, but production delay due to LHC consolidation in 2012.
