Single-shot spectral measurement of FEL pulses in SASE mode. (a) Typical SASE pulse spectral measurement at ∼92 eV for a longer pulse width. (b) The SASE pulse spectral measurement at ∼92 eV for a shorter pulse width. (c) The spectral measurement for 30 sequential single-shot FEL pulses in SASE mode, at ∼249 eV. |
