9. Applied Superconductivity Group • Aim:Scientific and technical research on applied superconductivity. • Structure: • There is a common laboratory shared by two Institutes: CIEMAT-CEDEX • CIEMAT contribution consists of 8 people while CEDEX one is 5. • CIEMAT site is mainly devoted to calculation, design and fabrication, whereas CEDEX one focuses on assembly and testing. • The group has been working under this framework since 1996.

10. Capabilities • Calculation: • Electromagnetic analysis (high and low frequency). • Mechanical analysis. • Quench modelling (superconducting devices). • Prototyping: • Design and fabrication follow-up of tooling. • Fabrication follow-up and assembly of electromechanical devices. • Coil winding. • Testing: • Superconductivity Laboratory: two cryostats, a GM cryocooler, power supplies up to 2000 A.

11. List of developments • High Temperature Superconductors: • Warm bore solenoid (gyrotron upgrade TJII) • HTS current leads (LHC, TESLA500) • Bearings (ACE2 Superconductor) • Low Temperature Superconductors: • SMES (AMAS500) • Magnets for LHC: tuning quadrupole, 2 trim quadrupole, superferric octupole, and tests of correctors (sextupoles, decapoles, octupoles). • Magnet package for TESLA500 and XFEL. • Design of the EFDA (European Fusion Development Agreement) dipole. • Design of high field magnets for NED (Next European Dipole) program. • Cryogenics (XFEL, AMS)

13. TESLA500 • Calculation and detailed design of a combined superconducting prototype magnet for TESLA500: a quadrupole and two dipoles. (2002-04)

14. ILC • The TESLA500 prototype magnet will be tested in SLAC to carefully measure: • The stability of the magnetic axis (should be better than 5 microns according to ILC requirements). • The field quality at low currents (persistent currents effect). • An Expression of Interest have been sent to the Global Design Effort group concerning the engineering design of the main linac magnet.

15. XFEL contribution (I) • Design of a combined superferric magnet (2005). • Fabrication of four prototypes (starting in 2006).

16. XFEL contribution (II) • Fabrication and test of the first prototype (2007)

17. HTS magnet for a gyrotron upgrade • Design and fabrication of a cryostat for a cryocooler (CIEMAT, 2005) • Fabrication and testing of HTS coils (CIEMAT, 2005-06) • Design of a HTS solenoid for a gyrotron upgrade: 2T, 150 mm aperture. (CIEMAT, 2007)

18. Next European Dipole • Phase I: characterization and fabrication of high current density Nb3Sn cable, besides conceptual studies on high field magnet design. • Contribution to the Working Group on Magnet Design and Optimization. • Phase II (FP7): design and fabrication of Nb3Sn corrector magnets for future particle accelerators or upgrades.

20. Possible future contributions to large facilities (I) • XFEL: • Superconducting magnets and power supplies • Intersections • LHC UPGRADE: • NbTi corrector magnet package (in collaboration with Rutherford Appleton Laboratory). • IFMIF (International Fusion Materials Irradiation Facility): • Magnets for DTL (not decided if superconducting or resistive yet)

21. Possible future contributions to large facilities (II) • FAIR: • EoI on 10th December 2007: Superconducting magnets are our preferred candidate to start with (as long as our accelerators group has just been created). • Super-FRS superconducting multiplets (quadrupoles, correctors, etc). A new facility would be needed for vertical assembly of 6 meter long cryostats. • NESR/RESR resistive magnets and other components can be a later contribution once the accelerator group is settled and the rings defined. • In any case, the scope of both developments should be in accordance with the financial contribution expressed by our funding agency. • A Super-FRS magnet prototype development could be started on April 2008. It could be a type 3 quadrupole (0.8 m with octupole, PSP 2.4.2.2.3) or a sextupole (PSP 2.4.2.3.2).

22. Possible future contributions to large facilities (III) • FAIR: • Proposed schedule for the quadrupole prototype. A preliminary calculation was developed in St. Petersburg and a conceptual design was done by Toshiba
