R&D / Surface Physics

Originally from Figeac in Lot, Jérôme holds a PhD degree from Paul Sabatier University (Toulouse, France) in materials science. Before joining Polygon Physics, he worked across the globe, from Japan to Europe as a materials scientist focused on metallic clusters and their interactions with gas molecules on their surfaces. His enthusiasm for challenging experiments and problem solving combined with expertise in ultra-high vacuum, plasma and charged beams is the nicest combo to develop the particle sources of the future.

R&D

Originally from Cotentin in Normandy, Noémie is a R&D engineer at Polygon Physics. Curious and dynamic, she enjoys conducting experiments to learn more about how things work down to the infinitely small. After studying plasma physics at university, she did a PhD and worked several years in laser-matter interaction. She has now set aside lasers to develop particle sources at Polygon Physics.

R&D / software

Robin Perret is a R&D engineer. He has a professional experience in several sectors, scientific but also logistics, robotics and sports, which allows him to bring his contribution to the development of Polygon Physics. His degree and interest in physics and his experiences in IT, mechanical and testing engineering allow him to manage projects from start to finish. Curious and multifaceted, Robin likes to imagine solutions and lead them from start to finish until their final development.

Materials / Product development

Cyprien Chassin is a product development engineer. After studying materials, he worked in different fields, simulation of elastomeric materials, performing tests on rocket engine prototypes and simulation of gas mixture in the injector. After moving to Grenoble, he worked on the optoelectronic performance and environmental resistance of space IR detectors. Versatile, and with an innovative spirit, Cyprien has now joined Polygon Physics, where he will test particle sources and develop automated tools such as image processing and more.
