Fast parallel EELS spectroscopy on individual atoms or clusters made of a few atoms in rapid motion on a thin carbon foil : (left) HAADF image of the analyzed area, (right) a selection of two spectra recorded at the apex of the white spots at the end of the blue and red arrows in (a). These individual spectra are extracted from a collection of 217 × 230 spectra in a spectrum-image recorded at the rate of 100 ms/spectrum, 0.35 Å/pixel (see [36]).
