Abstract

This report deals with the R&D activities aimed at developing the high field rapidly-cycling super-conducting dipoles needed for SIS300 synchrotron of the FAIR facility at GSI. The present lattice design includes 48 long dipoles with magnetic length 7.757 m and 12 short dipoles with magnetic length 3.879 m. The coils have two main features: they are curved (the corresponding sagitta is 112.8 mm for long dipoles), and they are fast ramped (for a superconducting magnet). Both these characteristics demand a challenging R&D, aimed at the development of the required low loss conductor, a robust design with respect to fatigue issues and a suitable winding technology. The Italian National Institute of Nuclear Physics (INFN) is performing this R&D. A project, called DISCORAP (“Dipoli SuperCOnduttori RApidamente Pulsati”), started in 2006 in accordance with a specific INFN-FAIR Memorandum of Understanding signed by both institutions in December 2006. The aim is to have a complete cold mass model of the short dipole ready in the summer of 2009. After a preliminary test of the cold mass in a vertical cryostat, it will be integrated into a horizontal cryostat for a test series at GSI.
