Superconducting Magnets

We have a long history of designing and building superconducting magnets for particle physics experiments.

Superconducting Rutherford Cables​​

​"Rutherford Cable" was developed here and is a key technology for superconducting accelerators such as the LHC at CERN and in the wider superconducting magnet industry. It enables high currents, magnet stability and enables shorter pieces of superconducting wire to be used.​

Cylindrical cage with domed top designed to be lowered into a cryostat vessel filled with coolant.  Mounted inside is an assembly containing a flat undulating magnet.

A plan​ar superconducting LTS undulator magnet for light sources and X-FELs mounted in a test cryostat, featuring very high accuracy winding.



Helical and planar undulator magnet prototypes have been designed and constructed. The prototype Helical Undulator is 4m long and provides a 0.86T helical field with a pitch of 11.5mm. A Planar U​ndulator for light sources featuring extremely high tolerances has been built and tested.

Two of these toroidal magnets have been installed on the ATLAS detector on the Large Hadron Collider at CERN.


​Atlas End Cap Toroids

Two of these very large toroidal magnets are installed on the ATLAS detector on the Large Hadron Collider at CERN. The 4T toroidal field is radial from 1.5m to 5m and the magnet conductor carries 20,000 Amps. The ATLAS End Cap Toroids were designed and engineered by STFC and featured a custom cryogenic epoxy also developed by STFC that has found many applications​.
