Scientific activity

We develop ion and electron sources based on laser excitation and ionization of Rydberg atoms. The originality of these sources lies in the highly monokinetic and correlated nature of the particles produced. This makes it possible to produce an optimal beam with total trajectory control. We aim to use this technology in ion and electron microscopy for imaging, spectroscopy and implantation applications.
