Figure 2

Photon spectra (histograms) for different incident proton energies impinging into a silver surface with incident angle of 80° from the material surface (10° from the target normal) and for a run using 107 particles. The photon energy bin size is 1 keV (as shown in the insets). The figure displays the contribution by the different proton energies within the photon energy bin of 1 keV. In the insets are shown the spectra in the same configuration and for an incident proton with energy 3 MeV and respectively 109 (upper inset) and 106 (lower inset) particles. The vertical dashed grey lines are guides for the eye for identifying the Ag Lα line.
