Figure 4
The accumulated Bragg signal as a function of resolution (q) and pulse intensity (I0) for four different pulse shapes and photon energies (2, 6 and 12 keV). The Bragg intensity is calculated over the entire pulse length (100 fs) based on equation (8), without taking into account the term . For 12 keV, and low intensities, the expected ionization is very low. Here the plasma model is not valid. Top row: 2 keV. Middle row: 6 keV. Bottom row: 12 keV. |
