Charge migration in aminophenol following sub-fs X-Ray pulses: Influence of nuclear effects and the XFEL shot-to-shot variation

摘要: 1. XFEL shot-to-shot variation• each pulse→ individual electron bunch (shot)→ variation (jitter) of intensity, envelope, and phase• 100 realistic 260 eV XFEL pump pulses: E (t)= Re [G (t) e iω0 t](1)→ start-to-end simulations of the XFEL at LCLS with the Genesis v4 code• reference: 0.85 fs Gaussian sinusoidal pulse fitted’to XFEL pulse widths
