Bruker Advanced Supercon designs magnet systems according to the customer's magnetic field requirements. We base our magnetic design on the layout of a coil or of a coil system regarding the electrical and geometrical constraints as specified by the customer.

 

The vector fields TOSCA / OPERA/ ELEKTRA software packages are applied for solving 2D and 3D static or transient magnetic field problems with and without iron. These packages are well established and have been proven in many fields of magnetic design.

The design of accelerator magnets, especially LHC prototype magnets, is based on the ‘Routine for the Optimization of magnet X-sections Inverse field computation and coil End design’ (ROXIE). This is a software package for design of superconducting multipole accelerator magnets developed at CERN.

The design of the magnetic field is performed in close interaction with the mechanical and manufacturing design to account for the interaction of the electro-mechanical forces with the mechanical structure of the magnet.

Applying our software tools we perform design studies of complete magnet systems starting from a certain magnetic layout with specific geometrical constrains given by the customer. Especially for superconducting magnets, structural analysis of the cold mass plays an essential role for the magnet design. From the calculated magnetic field the electro-mechanical forces are derived and used in a Finite Element Model code for the mechanical analysis.

 

Example of development work with designing a cold mass of superconducting accelerator magnets:

 

• LHC Dipoles for CERN, 3D-structural analysis of coil ends 
• SSC Main Ring Quadrupoles for SSCL, USA
• LHC Main Quadrupoles (Redesign of Collared Coil Structure)
• Ion source magnets for INFN, Catania; IMP, Lanzhou
