Sigmaphi

Specialising in the design and manufacture of electromagnets, we meet the specific needs of particle accelerators in the research, health, industry and energy sectors.

Our products are used in the most powerful particle accelerators, such as the Synchrotron at the Paul Scherrer Institute, the Large Hadron Collider (LHC) at CERN, the SPARC reactor at Commonwealth Fusion Systems and the Normandy Hadrontherapy cyclotron (NHa).

We are convinced that the well-being and fulfilment of our employees are key factors in our success. That’s why we do everything we can to create a positive and stimulating working environment, where everyone can develop both professionally and personally.

Sigmaphi is a socially responsible company committed to respecting the environment and contributing to sustainable development. We implement concrete actions to reduce our environmental impact and promote sustainable practices within the company.

Sigmaphi est une entreprise socialement responsable qui s’engage à respecter l’environnement et à contribuer au développement durable. Nous mettons en œuvre des actions concrètes pour réduire notre impact environnemental et promouvoir des pratiques durables au sein de l’entreprise.

As part of this same approach, Sigmaphi has signed a CSR charter with the UIMM (Union des Industries et Métiers de la Métallurgie) and is committed to respecting the principles of Corporate Social Responsibility (CSR).

Sigmaphi is supported by a number of players committed to the development of high added-value businesses. The company is supported by the national ETIncelles a national scheme designed to support the development of industrial SMEs. The Brittany Region which is keen to support innovation and job creation in the region, is providing Sigmaphi with financial support and strategic guidance. Breizh Rebond which has been Sigmaphi’s main shareholder since 2022, is helping it to consolidate its business and seek out new development opportunities.

For over 40 years, Sigmaphi has built its growth around its highly skilled engineering and production teams to deliver cutting-edge magnetic systems for particle accelerators. Our expertise spans from initial design to final measurements, ensuring the outstanding quality of our products.

Rooted at the heart of scientific ecosystems, Sigmaphi is much more than a mere supplier of electromagnets. Our close relationships with various stakeholders enable us to understand their challenges and objectives in depth. We foster long-term relationships built on trust and collaboration, supporting organizations in their most ambitious projects. Our expertise and innovative capabilities allow us to develop tailor-made solutions adapted to specific needs.

By equipping particle accelerators in research, healthcare, industry, and energy sectors, we are contributing to a more sustainable and responsible future. Our solutions enable the development of new cancer therapies, such as proton therapy, the production of clean energy through fusion reactors, the study of fundamental properties of matter to create high-performance new materials, and many other applications in these fields.
