Superconducting magnet system U-25 MHD facility

The Argonne National Laboratory has designed and is constructing a superconducting dipole magnet system for use in the bypass loop of the U-25 MHD facility in Moscow. Presented in detail are the system design parameters. Reviewed are the magnet geometry, stability criteria, cryostat thermal and mechanical design, cryogenic system parameters, and controls. Details of the servo mechanism winding machine, the epoxy fiberglass tension member support system, and the diagnostic instrumentation system for monitoring of the magnet's thermal parameters, structural forces and component accelerations during system cool-down and with the Magnetohydrodynamics (MHD) channel in operation are included.
