7 WP leader and Task 1 (Lucio Rossi - CERN) The WP COLMAG is composed by Collima@on and Magnet : the share of the 2.5 M (fixed by ESGARD)to requires to EU funds is: 0.8 M collima@on and 1.7 M Magnets Ther deputy WP will be a person from Collima@on. Task1. Coordination and Communication. Task leader : CERN Participants: CEA, INFN,?? Coordination and scheduling of the WP tasks monitoring the work, informing the project management and participants within the JRA WP budget follow- up 7

8 Task 2 (Luca Boiura - CERN) Task KA - 20T class superconductor development. Task leader : CERN Participants: CNRS, KIT, INFN, UniSouthampton, UniGeneva, UT Development of Bi strands with suitable basic characteristics (see IV. 1) Development of 10 ka cable in Bi with controlled inter- strand resistance R c, high compaction factor and stress reinforcement. Development of YBCO tapes with suitable basic characteristics (see IV. 1) Development of 10 ka cable in YBCO with controlled inter- strand resistance R c, high compaction factor and stress reinforcement. Characterisation of the strands, tapes and cable at cryogenic temperature 8

9 Task 3 (Jean Michel Rey CEA Saclay) Task 3. 5 T HTS dipole magnet. Task Leader : CEA Participants: CERN, INFN,... CNRS Design of the 20 T HTS insert for HE- LHC magnet, with definition of possible range of suitable parameter : J, magnetization, R c, geometrical tolerance (random and systematic), strain level. Design the 5 T dipole model 45 mm free bore, 0.5 to 1 m long with the same conductor characteristics of the 20 T insert. Evaluate cosϑ vs. race track topology, protection, etc...
