  1. Is 3T peak – 3T/s a dream ? D.Tommasini

  2. RHIC dipole • Superconducting wire: • NbTi-Cu (1:2.25) • filament diameter 6 mm • twist pitch 13 mm • no coating • Rutherford cable • no core • Coil • phenolic spacer • Cu wedges • Yoke • Hc= 145 A/m • 6.35 mm laminations • RHIC type dipole GSI 001 • Superconducting wire: • NbTi-Cu (1:2.25) • filament diameter 6 mm • twist pitch 4 mm • Stabrite coating • Rutherford cable • 2 x 25µm stain- • less steel core • Coil • stainless steel collar (G11 keys) • G11 wedges • Yoke • Hc= 33 A/m, 3.5% Silicon • 0.5 mm laminations, glued

  5. R&D on wires for 3T/s – 3T peak We may aim at the following distribution of losses Filament hysteresis : 50% Interstrand resistance : 15 % Matrix coupling : 15 % Structure : 20 % 2006 R&D Specify and procure one billet with filament size ~ 3 microns, Cu matrix Explore CuMn matrix Explore high interstrand resistance versus core (stability, long term behaviour)
