CICC superconducting dipole

Elytt Energy has developed the design of a superconducting dipole with CICC cable for the NESR ring of the FAIR project managed by GSI.

Germany is interested in building an international accelerator facility for beams of ions and antiprotons with two main synchrotron rings and several experimental rings.  The international FAIR Project (Facility for Antiproton and Ion Research) will make use of the existing accelerators of GSI at Darmstadt.

For the development of such a Project, Germany is intending to count on the collaboration of several European countries.  Spain, in particular, is interested in contributing to the design and manufacturing of the NESR experimental ring main magnet systems (magnets, power supplies, vacuum chambers,)
