Superconducting sector magnet for the deuteron cyclotron DC-1

The results of calculations of a superconducting magnet with a 'cold' pole for a cyclotron to deuteron energy of 100 MeV are presented. The maximum induction in the magnet is 4.5 T; the stored energy is 5 MJ; and the mean current density in the coil is 9*10/sup 7/ A/m/sup 2/. The scheme and main parameters of the magnet protection system and cryogenic provision system are described. The results of calculation of magnetic and thermal forces acting on the coil and its case are presented. The status of the manufacture of the magnetic system elements is considered.<
