Noémie Jourdain, a native from the nearby Vercors Massif, obtained his PhD from Institut Néel in Grenoble. At Polygon Physics he can combine his interests in high technology products and programming, working on our Research & Development. His focus is primarily on multi beam sputtering: a new ion beam sputter deposition method based on our unique ECR technology. Polygon Physics benefits from Noémie’s former career as mountain biker at the French national level, which has taught him to be meticulous in his work. You get nowhere without properly prepared equipment.
