  1. INTRODUCTION TO THE 4° GSI-INFN MEETING FOR SIS300 DIPOLE DEVELOPMENT The aim of this meeting is to close the first part of the activities aiming to perform feasibility studies and preliminary developments and to move towards the conceptual design. In this frame INFN thinks that several parameters shall be now frozen and the meeting shall have as result the definition of the agreed parameters. This point is very important because any delay in defining what exactly we want to do will introduce delay in the global R&D program. The agenda has been organized in a way to discuss the relevant points and to get a conclusion for the starting of the conceptual design phase

  2. I The INFN R&D program for curved SIS300 dipole. Two steps Conductor Studies, Design and Models Final goal: 3.5 m long 4.5 T curved dipole in its horizontal cryostat Construction Tests II

  3. List of frozen parameters and technical choices • Coil Inner Diameter 92 mm • Length of the prototype 3.8 m (effective length) • Bending radius 66.7 m • Number of turns 32 • Number of blocks 3 • Cored Conductor (Same dimensions of LHC outer layer) • 6.1 Wire Diameter 0.825 mm • 6.2 Non-Cu/Sc ratio [1.2-1.6] • 6.3 Number of strands 36 • 6.4 Temperature margin 1 K • Thickness of the SS collar 30 mm (holding all the force) • Coil wedges and fillers in G11
