Introduction

Are you interested in the operation of 1000’s of superconducting magnets and their protection systems, and in programming techniques to study and analyse existing and future superconducting magnets and circuits?

Within the TE Department, the MPE group provides support to the operation of the entire accelerator complex and develops, operates and maintains state-of-the art technology for magnet circuit protection and interlock systems.

The superconducting magnet circuits of CERN’s largest accelerator, the Large Hadron Collider (LHC), operate with currents of up to 12 kA and stored energies of more than 1 GJ. The TE-MPE-PE section develops tools to better understand the behaviour and protection of these circuits, conducts studies of emerging protection issues, and monitors the evolution of their performance, see also https://twiki.cern.ch/twiki/bin/viewauth/TEMPEPE/. Furthermore, the section participates in all design studies for the magnet circuits of upcoming upgrades of the LHC and future accelerators.

Functions

As applied physicist in the TE-MPE-PE Section, you will:

• Develop software to monitor the behaviour of the superconducting magnets and circuits in the LHC;
• Analyse the long-term behaviour of the above-mentioned circuits, in correlation to current cycling, thermal cycling, quenches, and radiation doses; accordingly make recommendations for mitigations or improvements;
• Contribute to the further development of specific computer tools/models as part of the framework for the simulation of steady-state and transient effects in superconducting wires, cables, magnets, and circuits;
• Cross-check the above-mentioned tools against other existing computer codes (if available) and validate the tools by means of experimental data obtained during tests on various coils and magnets;
• Share knowledge by supervising or mentoring students working on development of technology and tools for operation and protection of high-field magnets.

Master's degree or PhD or equivalent relevant experience in the field of Applied Physics, Electrical Engineering or a related field.
