Simulation of Accelerator Magnets with SIMULIA Opera

Simulia Opera is a finite element analysis package which can be used to develop 2D and 3D models with simulation of multiphysics effects including electromagnetics, space charge, stress and thermal.

Opera has been used for more than 35 years to design accelerator magnets for both industrial and research applications. Opera has been used to successfully design all types of magnets for accelerators including permanent magnet, DC and AC dipoles, quadrupoles, and higher order magnets, undulators and solenoids. Opera can track particles through the simulated fields, with or without space charge effects.

Opera can simulate both low and high temperature superconductors, including superconducting quench events where a superconducting magnet rapidly transitions to the normal state. This type of simulation accounts for the effects of induced eddy currents and heating.

An overview of Opera's capabilities with accelerator magnets will be given in this e-seminar. Development of a magnet model from basic concepts will be demonstrated as well as more advanced features such as superconducting quench.

Highlights:

• 2 and 3D simulation of magnets with SIMULIA Opera
• Magnets including bending, focusing and higher order multipoles, undulators and superconducting magnets
• Example of 2D simulation of quadrupole including python scripting; import of model to 3D
• Calculation of Fourier field coefficients
• Advanced example of superconducting quench
