Figure 3
Typical example of a single-shot image (upper-right panel) of Au 4f photoelectrons emitted by soft X-ray irradiation onto the thin Au sample. Such an image was sequentially acquired in shot-to-shot sweep mode. The CCD camera was exposed for 14 ms. Both upper-left and lower panels are projected spectra of a two-dimensional single-shot image onto the `Y channel' and `X channel (or energy channel)'. |
