(a) Calculated transmission of the beamstop materials in a range from 5 keV to 25 keV (Henke et al., 1993). (b) Energy deposited per atom in a single pulse. For simplicity our calculation used 1010 photons spread over a beam of 1 mm × 1 mm. In (b) we included the approximate ablation threshold for a focused beam of 10 µm × 10 µm and 1012 photons per pulse at 1 × 10−6. |
