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.

Lorenzo Bortot
CERN

Lorenzo Bortot received BSc and MSc degrees in electrical engineering from Universita’ degli Studi di Padova, Italy, in 2010 and 2012, respectively. He joined CERN in Geneva, Switzerland, in 2015 as a research fellow, working on numerical modeling of electrodynamic phenomena in accelerator magnets. Currently, he is working toward his PhD degree at the Institut für Teilchenbeschleunigung und elektromagnetische Felder (TEMF) with the Technische Universität Darmstadt, Germany. His research interests are finite-element magnetothermal field simulations in low- and high-temperature superconducting magnets, quench protection techniques, and optimization problems.
