Simulation of Superconducting Magnets in COMSOL Multiphysics® - Archived
Please note, this webinar will take place live and will not be recorded.
Superconductivity is known since about one century, and its last decades’ evolution is making it attractive not only for the market nieces where it is established, but also as a driving force for boosting new technologies and helping global electrification goals.
Particle colliders for high-energy physics are important tools for investigating the fundamental structure of matter. They contain the most cutting edge magnet technologies as their working principle requires very strong magnetic fields that confine the particle beam within a machine of acceptable dimensions. For the magnets, the Large Hadron Collider at CERN relies on normal and low-temperature superconductors (LTS), mostly Nb-Ti. To increase performance high-temperature superconductors (HTS) are needed allowing magnetic fields as strong as 20 Tesla and beyond. Independently from the adopted technology, numerical methods play a crucial role in supporting the safe and reliable operation of accelerator magnets with respect to thermal stability, quench detection and the subsequent quench protection measures.
The webinar will open with a brief introduction covering the most relevant aspects regarding physics of superconductors and dynamics effects in accelerator magnets. Subsequently, the field formulation and the numerical implementation in COMSOL will be discussed, with regards to both high- and low-temperature superconductors. Afterwards, examples of practical applications such as insert and accelerator magnets will be discussed, highlighting the new technological trends like the non-insulated coil concept.
You will have the opportunity to ask your questions.
