## NED

**NED is a Joint Research Activity (JRA) of the Coordinated Accelerator Research in Europe (CARE) project, funded under the auspices of EU- FP6 Research Infrastructures. Launched in January 2004; most tasks were completed by June 2007; total budget of ~2 M€ and an EU grant of 979 k€.**
**Three technical Work Packages (WP) are still active  **
**WP 2:  Thermal Studies and Quench Protection (TSQP),       **
**WP 3:  Conductor Development (CD),       **
**WP 4:  Insulation Development and Implementation (IDI),**

## NED: Insulation and Thermal Studies

**Insulation development**
**CCRC/RAL has identified a polyimide sized glass fibre tape that is able to sustain the required Nb****3****Sn heat treatment without degradation**
**CEA is pursuing the development of ceramic He-porous insulation. Encouraging results were obtained for the thermal qualities, more work is needed on the mechanical properties**
**Thermal Studies**
**A He-II double bath cryostat was built and is  operational since end 2006 (Univ. of Worclaw and CEA)**
**Heat transfer measurements on cable stacks and insulation samples are ongoing at CEA**

## NED: Conductor Development (1)

**The Conductor Development Work Package is the core of NED( ~70% of the EU-allocated funding) and it includes three main Tasks**
**wire development (two industrial contracts under CERN supervision: Alstom/MSA, Fr and SMI, NL/D)**
**wire characterization (CEA, INFN-Ge, INFN-Mi, and TEU)**
**cabling studies (CERN and INFN-Mi)**

## NED: Conductor Development: SMI

**Cabling test done at LBNL end of June 2007 with  the SMI strand.**
**Strand before cabling:**** **
**288 ****filaments**** (~ 50 μm****) **
**D****strand**** = ****1.257 mm, ****Cu/non-Cu****  ratio of ****1.22**
** ****I****c****=1397 A @ 12 T, 4.2 K (~ ****15 %**** below spec.), ****n=80****,          **
**	****J****c****~ 2500 A/mm****2     ****RRR ~ 80**
**5 cable sections were manufactured varying the cable compaction by changing mainly the mid-thickness of the cable. Each cable section has a length of ~2 m.**
**All sections were characterized by metallographic examination and a first series of critical current measurements was performed by CERN on extracted strands.**
**The first results on cabled strands indicate a ****reasonable degradation between 4 and 8%,**** which is already a very good result.**
**The green light was given to SMI-EAS to start the total strand production (12,7 km) (end Febr. 2008)**
**The cabling will be done under CERN’s responsibility (either at LBNL or at CERN).**

## NED: Conductor Development: Alstom

**Has produced strands up to 2100 A/mm****2**
**New strands expected in November.  Expected Jc ~ ****2500 A/mm****2**
**Production of strands expected by mid 2008**

## NED 1.5 Short Model Coil

**CCLRC-RAL, CERN and CEA have started a program extension (NED phase 1.5 ) on Short Model Coils**
**SMC program aim is to test cable in a coil without the complications of a Cos******** geometry and to get experience with coil fabrication **
**	****(420 mm x 190 mm x  10 mm,   peak field 13 T)**
**First model manufacturing to start in spring 2008**

## CERN High field magnet program

**CERN is starting a High Field Magnet R&D activity**
**Aim: prepare for LHC interaction region upgrade to increase luminosity**** ****and possible longer term programs**
**Using Nb****3****Sn technology**
**Complementary to existing programs (NED, LARP, Japan)**
**Avoid effort duplication**
**Get CERN up to date in the HFM technologies**
**Timescale****:**
**Part of the ‘white paper’ package approved by the CERN council in June 2007**
**To run in 2008-2011**
**In autumn 2007 a budget will be attributed**

## R&D on Nb3Sn: magnets needed

**New magnets are needed for the LHC phase 2 upgrade in about 10 years**
**Quadrupoles for the low-beta insertions**
**Corrector magnets for the low-beta insertions **
**and possibly**
**Dogleg dipoles for the cleaning insertions**
**Q6 for cleaning insertions**
**10 m dipoles for the dispersion suppressors**
**Early separation dipole (D0)**
**New magnet types needed for a neutrino factory**
**Open midplane dipole for a muon decay ring **
**Open midplane dipole for a beta beam decay ring**

## Summary: requirements

**Common points:**
**All magnets need radiation hardness, good heat removal and a large temperature margin**
**and**
**The Low-beta quad, dispersion suppressor dipole and early separation dipole need the Nb****3****Sn high Jc at 12 T**

**Also for Phase I**

**Phase II**
