The aim:
Imaging for the first time the surface vibrational states with nanometric spatial resolution
This will be done by full filed imaging of loss energy electron energy losses in real and reciprocal space at high spatial (15 nm) spectral (5 meV) and wave-vector (40 cm-1) resolutions.

Funding
Le projet SESAME, coordonné par Lionel Amiaud (ISMO), avec Daniel Comparat (LAC) et Nick Barrett (SPEC), a obtenu un financement de 1,1 M€ permettant d’envisager la construction du prototype dans les 3 ans à venir.
The cumulated investment since 2014 is illustrated below:
The multidisciplinary nature of the project will contribute to structuring collaborations in the Paris Saclay campus, in the Ile-de-France region and also internationally with both research institutes and industry.
We’d like to thank all of the supporting laboratories, institutes and companies. Here are just a few examples from colleagues and collaborators:
