  1. FP7-IA HFM JRA proposal • Outline • Motivation • General description • Proposed Work Packages FP7-IA HFM JRA proposal G. de Rijk (CERN)

  2. Future magnet needs 2 categories: max field <9 T : Nb-Ti technology Max field >9 T up to 15 T : Nb3Sn technology Common points: Radiation hardness, heat removal and temperature margin and The Low-beta quad, dispersion suppressor dipole and slim dipole need the Nb3Sn Jc at maximum coil fields >9 Tand in some cases >13 T FP7-IA HFM JRA proposal G. de Rijk (CERN)

  3. Work program To be seen in conjunction with the CERN program on HFMs • Support Studies • Study thermal properties • Study radiation resistance of components and coils • Model magnet • Design build and tests short dipole model (1 m - 1.5 m) • Prototype magnet • Design build and tests long prototype magnet (4 m - 8 m) Dipole or quadrupole: to be decided later depending on LHC needs FP7-IA HFM JRA proposal G. de Rijk (CERN)

  4. NED history and future requirements • FP6 NED project for a 1 m long, 12 T bore field, 88 mm aperture model • reduced version was approved (25% funded): preparation of the technologies needed for the model • Conductor development • Design studies (i.e. magnet design, thermal studies) • Component development (i.e insulators) • NED magnet was intended to upgrade the FRESCA facility to a 12T cable test station • The FRESCA facility upgrade is still strongly needed: key element for HFM conductor development and QA • Putting together the FRESCA needs and some common issues on the envisaged dipole needs: • Build a 1 m-1.5 m long, 13T bore field, 110 mm-130 mm aperture model magnet, to • Upgrade FRESCA • Constitute a test bed for the LHC and dipole magnets • Conductor: Profit from NED development and CERN HFM program FP7-IA HFM JRA proposal G. de Rijk (CERN)

  5. Prototype magnet • An important step towards an accelerator magnet is a full length prototype • For the LHC the choice is still open to what is the most relevant type: • 4 m - 8 m long, 200 T/m gradient, 130 mm aperture quadrupole or • 4 m - 8 m long, 13 T bore field, 130 mm aperture dipole • To test the scale-up of • Long conductor length of Nb3Sn cable • Coil manufacturing technology, winding, reacting (650C), handling of long coils • Support structure scale up FP7-IA HFM JRA proposal G. de Rijk (CERN)
