45 Tesla Hybrid Magnet for Nijmegen

Design of the 45 tesla hybrid magnet for Nijmegen. Design of the 45 tesla hybrid magnet for Nijmegen.

The MagLab is playing a key role in the design and construction of a new 45 tesla hybrid magnet to be located at the High Field Magnet Lab at Radboud University in Nijmegen, The Netherlands.

Nijmegen engineers will design and build the 21 MW resistive inner coil set for this magnet; the MagLab is building the superconducting outer coil for this system, which will produce a magnetic field as powerful as the MagLab’s world-record 45 tesla hybrid magnet.

High Field Magnet Lab at Radboud University

The MagLab-built outsert will incorporate the cable-in-conduit conductor (CICC) design that it has used in coils for the lab’s 36 tesla series connected hybrid magnet scheduled for commissioning in 2016. Like the MagLab’s SCH coils, the Nijmegen outsert will use niobium tin superconductors, but will be 25 percent larger than those of the MagLab’s series connected hybrid.

The MagLab will wind, react and impregnate the coil, assemble the cold mass and fabricate the HTS leads.

The project is not the first collaboration with the Nijmegen lab. The MagLab also collaborated with the European lab to build them three 18 MW, 33 tesla resistive magnets.
