Abstract :
Four normal conducting main dipole magnets were designed and built for the Cooler Injector Synchrotron CIS allowing proton acceleration up to 220 MeV with a magnetic field of Bmax≈1.78 T. Field calculations in two (2D) and three (3D) dimensions were used to optimize magnet laminations and end packs. End packs are designed to determine edge angle, effective field length (EFL) and to compensate hexapole components. The magnets are assembled of machined laminated wedges to accommodate the strong curvature. Field maps were performed in the range of B=0.25 T-1.8 T. The magnet parameters are well within expected specifications and initial tests at injection energy of CIS were conducted successfully
