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.

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)

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.

XFEL contribution (I)

Design of a combined superferric magnet (2005).

Fabrication of four prototypes (starting in 2006).

Future projects

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)

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).

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
