Company Description

At CERN, the European Organisation for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature.

Job Description

Introduction

Are you motivated by precision mechanics and interested in contributing to innovative magnet technology for particle accelerators? Join us in building the next generation of superconducting magnets at CERN.

The Magnets, Superconductors and Cryostats (MSC) group in the Technology Department (TE) is responsible for the design, construction, and testing of both superconducting and normal conducting magnets for CERN's accelerator complex. This includes magnet cryostat design, integration into accelerator systems, and quality control, and operational support for magnet performance and devices.

Within MSC, the Superconducting Magnet Technology (SMT) section is responsible for advancing high-field magnet technologies for future accelerators. These advanced systems use superconducting materials with complex mechanical and electrical properties, with complex mechanical and electrical properties, presenting significant manufacturing challenges. Addressing these challenges requires the development of innovative materials, processes, and tooling.

Functions

As mechanical technician you will be part of a multidisciplinary team focused on the design, development, and validation of new concepts, procedures, and tooling to produce small-scale models of CERN’s next-generation low temperature superconducting magnets. You will contribute to key prototyping activities for coil manufacturing and mechanical assembly in close collaboration with engineers and technicians.

Your main responsibilities will include:

• Coil production: winding, preparation for heat treatment, preparation for impregnation and finishing;
• Mechanical assembly: assembling structural parts, electrical connections, and instrumentation;
• Inspection and testing: performing quality checks and functional measurements;
• Tooling support: assisting in the design and refinement of dedicated tooling and assembly processes.

If you're passionate about precision engineering and hands-on prototyping, this is your chance to take part in innovative projects at the forefront of accelerator technology.
