SEF magnets are used in particular in reference synchrotrons at CERN in Geneva, the world's largest particle accelerator, ESRF in Grenoble and SOLEIL on the Saclay plateau. A partner in research and industry, SEF contributes through the products it manufactures to the advancement of knowledge in fields as diverse as basic research, material physics, chemistry, nanotechnology and medicine. SEF brings together a team of a dozen experienced people, operators, technicians and engineers, who have implemented the know-how and skills acquired and transmitted within the company for four decades. This human dimension combined with a solid technological mastery allows SEF to build lasting relationships with its customers and to offer them tailor-made solutions, adapted to their needs and constraints, whatever their demand. Resumed in 2020 by Eric Fanio, engineer in physics and electronics and specialist in industrial problems, the company entered a new stage of its development.
