Description du poste

The CEA, in collaboration with the CNRS, has launched SupraFusion, a 50-million-euro exploratory scientific program focused on high-critical-temperature (HTc) superconducting technologies.

The goal of this ambitious program is to stimulate the development of this technology in France, with a view to the numerous economic and societal benefits it could generate in various fields such as energy (thermonuclear fusion, wind power), medicine (medical imaging), and transportation (superconducting motors).

As part of this large-scale scientific project, the CEA plans to conduct several R&D campaigns on high-temperature superconducting (HTS) conductors, samples, and magnets by testing them at cryogenic temperatures (from 4 K to 77 K). To strengthen the current team, the CEA is seeking a technician specialized in the upgrading, development, and operation of a cryogenic test station.

Your responsibilities will include:

• Test Station Adaptation: Upgrade and configure the test station to meet the specifications required for each R&D campaign (cryogenic fluid management, instrumentation, power supply, LABVIEW control program, etc.).
• Preparation of samples or superconducting magnets: Ensure the mechanical integration, handling, welding, and instrumentation of samples and/or magnets in preparation for testing.
• Operation and Management of the Cryogenic Facility: Oversee test campaigns (cooling down, current ramp-up, physical measurements, LABVIEW data acquisition program, etc.).
• Equipment Maintenance: Perform maintenance on various hydraulic and electrical equipment.

Candidate Profile

You have a high school diploma or a bachelor’s degree. You enjoy working in multidisciplinary teams. You have previous experience working on experiments or test benches. You are able to adapt and learn in a cutting-edge scientific environment. You are organized, self-reliant, proactive, and meticulous, and you have excellent interpersonal skills and a strong team spirit.
