Abstract
A device for characterizing a surface of a sample, including; —a chamber comprising a medium for the sample, the chamber being connected to a pump, referred to as the primary pump, suitable for maintaining a pressure below 10-2 mbar within the chamber; —a source for generating an incident beam of neutral atoms or molecules having an energy of between 50 eV and 5 keV, with a divergence less than or equal to 0.05°, the source being arranged to direct the incident beam within the chamber through an inlet to the surface to be characterized with an angle of incidence less than or equal to 10° relative to the plane of the surface.
