Job Description

Internship Topic

Study of losses in a high-critical-temperature superconducting magnet.

Contract Term (in months)

6

The SupraFusion PEPR aims to develop new technologies and expertise based on high-temperature superconductors (HTS), in order to address the energy and societal challenges of the future, particularly through fusion energy. A major milestone of the project is the design and fabrication of a demonstration magnet incorporating REBCO (Rare-Earth Barium Copper Oxide) HTc materials, capable of carrying 50 kA in a 20 T magnetic field.

A key challenge lies in understanding and controlling losses and the magnetization process during transient phases (charging/discharging the magnet). Several factors are at play: hysteresis losses in the superconducting layer, coupling losses between REBCO strips, and Joule losses in the copper conductors.

The internship will involve conducting an in-depth study of these various loss mechanisms, based on a targeted literature review, analytical models, and 2D/3D numerical simulations, in order to optimize the operation of the demonstration magnet prototype. Experimental validation of the models may be considered as an option.

Unit Description

The Department of Accelerators, Cryogenics, and Magnetism (DACM) is part of the Institute for Research on the Fundamental Laws of the Universe (Irfu) within the CEA’s Directorate of Fundamental Research. It is located at the Saclay campus. These facilities have been renovated and consolidated into a large complex called “the Synergium,” which covers an area of 25,000 m². The DACM, which employs 90 research engineers and 40 technicians, is dedicated to conducting, in collaboration with the national and international research community, to conduct world‑class research and development in the fields of particle accelerators, cryogenic systems, and superconducting magnets for fundamental research. For many years, it has played a major role in building the high‑tech instruments required for this research.
