Figure 8
Photon flux measured at the sample position with a PIN diode for different SSA settings and energies at 300 mA ring current. Red curve: flux for highest degree of coherence. Blue curve: flux at partial degree of coherence and with 20% larger focus size than for high coherence. Black curve: flux for SSA opening resulting in 100 nm spot size for energies above 10 keV. Measured focus sizes (nm) and used SSA openings [H × V (µm)] are shown below the coherence mode flux markers. |
