A large superconducting dipole cooled by forced circulation of two-phase hefium is described. Details are given of the magnet design and construction. A short discussion of sorae cryogenic problems are presented together with the first results of the dipole's operation.

A large superconducting di .p.ole cooled by forced circulation of two phase hehum M. Morpurgo

A superconducting dipole cooled by forced circulation of two-phase helium has been constructed. Fig. shows a general view of the magnet, which is installed at CERN in a high-energy particle beam of the 300 GeV Proton Synchrotron. The main characteristics of the dipole are given in Table . coils were manufactured respectively by the firms Thyssen (Germany), Sulzer (Switzerland), and Ansaldo (Italy). The cost of the dipole, not including the refrigerator, was ~ 5 MSF. It was put into operation in June 1978 and has worked since, almost with interruption.
