  3. Contents • Introduction • TSQP Work Package • CD Work Package • IDI Work Package • Preparing Phase II

  4. Current Status • Following EU recommendations, the NED program has been divided into two phases • Phase I groups together all the tasks related to conductor development and includes some limited studies on conductor insulation, • Phase II groups together all the tasks related to the detailed design, manufacturing and test of a large-aperture (up to 88 mm), high-field (up to 15 T) dipole magnet model. • Phase I has been approved as part of the CARE project (~13 staff.year over 3 years; total cost: ~2 M€; requested EU funding: 979 k€). • A strategy is being devised among NED collaborators to find the funding necessary to carry out Phase II (~22 staff.year, material costs: ~1.2 M€).

  5. NED Phase I • The Phase I of the NED Program is articulated around four Work Packages • 1 Management & Communication (M&C), • 2 Thermal Studies and Quench Protection (TSQP), • 3 Conductor Development (CD), • 4 Insulation Development and Implementation (IDI). • The Activity is coordinated by A. Devred (CEA & CERN), helped by A. den Ouden (Twente University).

  6. Cost and Manpower Distributions Among NED WP Total Expected Costs (2,093 k€) Total Manpower (152 staff.month)

  7. NED Collaborators • Six institutes have agreed to collaborate to NED • CCLRC/RAL (UK), • CEA/DSM/DAPNIA (France), • CERN/AT (International), • INFN/Milano-LASA & INFN/Genova (Italy), • Twente University (the Netherlands), • Wroclaw University (Poland). • A seventh institute (CIEMAT, Spain) has expressed interest in joining the collaboration and is ready to commit 1.5 staff.year of manpower to Phase I and to contribute significantly to Phase II.

  12. Contents • Introduction • TSQP Work Package • CD Work Package • IDI Work Package • Preparing Phase II

  13. Initial Proposal for TSQP WP • In the initial proposal, the TSQP Work Package was supposed to address four main issues 1. What will be the level of power deposition from beam losses on NED coils?  beam loss computations (INFN/Milano-LASA; cut in final proposal) • How does Nb3Sn conductor insulation behave in He environment and how much heat can be transferred through it?  heat-transfer measurements (CEA & WUT; approved in final proposal) 3. What is the optimum magnet cooling scheme?  numerical model (WUT; cut in final proposal) • What the optimum quench protection scheme?  quench computations (INFN/Milano-LASA; approved in final proposal)

  14. Present TSQP Work Package • The present TSQP Work Package is divided up into three Tasks • 2.1 Work Package coordination • 2.2 heat-transfer measurements through N3Sn conductor insulation (CEA/DSM/DAPNIA & Wroclaw University of Technology, under CEA/DSM/DAPNIA supervision) • 2.3 quench protection computations (INFN/Milano-LASA) • It is coordinated by G. Volpini (INFN/Milano-LASA)

  15. Task 2.2: Heat Transfer Measurements (1/2) • The January SC meeting has defined the parameter space and has established a “wish list” for the heat transfer measurements. • The wish list includes • to perform fundamental R&Don “innovative” insulation to study its alleged porosity to helium I and II, • to characterize thermal performances in helium I and II of samples representative of insulated conductors in magnet coils subjected to static heat deposition (in the 50-to-80 mW/cm3 range). • The wish list has has been communicated on 21 January 2004 to the relevant persons at CEA/DSM/DAPNIA with the charge of defining a Program fitting within the allocated resources.

  16. Task 2.2: Heat Transfer Measurements (2/2) • 27 February 2004:Program proposal (CEA/DSM/DAPNIA) • 12 March 2004:Informal review by P. Lebrun (ESAC member) • 25 March 2004: Formal approval by NED Steering Committee • 31 March 2004: cryostat and cryogenic modules specifications (CEA/DSM/DAPNIA) • 31 December 2004: cryostat and cryogenic module fabrication • (WUT & CEA/DSM/DAPNIA) • 1 April 2005: Facility commissioning at CEA/Saclay • (WUT & CEA/DSM/DAPNIA; EU Deliverable) • 30 December 2005: Interim report on measurements (CEA/DSM/DAPNIA; EU Milestone) • 29 December 2006: Final report on measurements (CEA/DSM/DAPNIA; EU Deliverable)

  17. Task 2.3: Quench Computations (1/2) • Similarly to what has been done for Task 2.2, the January SC meeting has defined the parameter space and has established a “wish list” for the quench computations. • The wish list includes • to establish a comparison of existing quench codes in Europe, • to establish a European database on thermal material properties, • to studythe influence of Cu-to-non-Cu ratio, Cu RRR, magnet length, quench heater design and location, and quench back on NED baseline design. • The wish list has has been communicated on 13 February 2004 to M. Sorbi, who will be responsible to carry out this Task at INFN/Milano-LASA, with the charge of defining a Program.

  18. Task 2.3: Quench Computations (2/2) • 27 February 2004:Program proposal (INFN/Milano-LASA) • 12 March 2004:Informal review by L. Rossi and H.H. ten Kate (ESAC members) • 25 March 2004: Formal approval by NED Steering Committee • 31 December 2004: Interim report on quench computations • (INFN/Milano-LASA; EU Milestone) • 30 June 2005: Final report on quench computations • (INFN/Milano-LASA; EU Deliverable)

  19. Missing Tasks of TSQP Work Package • Two important tasks have been deleted from the initial proposal • beam loss computations, • coil cooling optimization. • We are looking into • building upon INFN/Milano-LASA experience to run limited beam loss computations for one conservative scenario of LHC IR upgrade, • building upon existing CERN/WUT collaboration to adapt an existing numerical model to NED baseline design.

  38. Re-enacting MDO Work Package (1/2) • Some manpower is now available for magnet design and optimization • 9 staff.month from CCLRC/RAL (included in NED Phase I contract), • 18 staff.month from CIEMAT, • plus • a graduate student who started a 3-year contract at CEA/DSM/DAPNIA in November 2003 on a topic closely related to NED (under the supervision of Pierre Védrine), • CERN/AT is looking for a technical student at Torino University, who would be invited to Geneva for two years and who could work at least for one year on NED (under the supervision of Paolo Fessia).

  39. Re-enacting MDO Work Package (2/2) • The available manpower (with profiles not needed elsewhere in the Program) enables us to re-enact the Magnet Design and Optimization (MDO) Work Package, that was included in the original proposal, but was finally deleted. • The January SC meeting decided to create an MDO Working Group, that will be chaired by Pierre Védrine (CEA/DSM/DAPNIA). • The membership and charge of the Working Group have yet to be defined. • Once formed, the Working Group will brainstorm to propose a Program, that will be reviewed by relevant ESAC members and approved by the Steering Committee.

  40. Towards Model Magnet Manufacturing • Preliminary discussions with CIEMAT have shown that they were also interested in participating to NED Phase II (detailed design and manufacturing of model magnet). • For instance, they would be ready to ask a grant from the Spanish government to cover the material costs needed to manufacture NED coils (~250 k€) and CIEMAT would contribute the manpower to do the job. • As CIEMAT has little experience with Nb3Sn technology, they need some training, which could be done by associating them to ongoing programs at CEA/DSM/DAPNIA and TEU. • Once the coils are manufactured, it should be easier to convince one of the big laboratories to complete model magnet assembly.
