Superconducting Magnets Development

SIS100: For SIS100 modified versions of the fast-ramped superferric magnets of the Nuclotron synchrotron at JINR Dubna will be used. The original Nuclotron dipole magnets produce an overall AC loss at 4 K of about 38 W/m (standard cycle: Bmax=2 T, dB/dt = 4 T/s, repetition rate of 1 Hz). It is necessary to reduce the loss at cryogenic temperatures at least by a factor of 2, the corresponding R&...

Superconducting Materials for Magnets

Superconducting materials for magnets will be discussed from three viewpoints: firstly the basic physical properties of the materials themselves, secondly the constraints and preferences imposed by the requirements of magnet building and finally, the manufacture of magnet conductors as a commercial product.

Superconducting Magnets for Detectors

A Fermilab/KEK/University of Tskuba, Japan collaboration is designing a large superconducting solenoid for the Fermilab Collider Detector Facility (CDF). A review of the status of other superconducting solenoids built for colliding beams machines is presented and progress on the design of the CDF magnet is discussed. Two types of superconducting coils appear to be feasible; a bath-cooled cryost...

Superconducting Magnets for High Energy

Center With the availability of high energy accelerators the need for powerful experimental, beam transport and special magnets is steadily increasing. Experimental high field large volume watercooled or conventional magnets would have power requirements which would be economically unsound. Superconducting magnets have reached a stage where they can be incorporated in connection with high energ...
