High wavevector temporal speckle correlation measurements are feasible at the Linac Coherent Light Source (LCLS). Analyzing fluctuations in X-ray free electron laser (FEL) power spectra informs methods for improving data quality in scattering experiments.

Area of Science:

  • X-ray science
  • Condensed matter physics
  • Materials science

Background:

  • The Linac Coherent Light Source (LCLS) is the first hard X-ray free electron laser (FEL).
  • FELs exhibit pulse-to-pulse spectral profile fluctuations due to their chaotic nature.
  • These fluctuations impact X-ray scattering experiments, particularly temporal speckle correlation measurements.

Purpose of the Study:

  • To investigate the feasibility of high wavevector temporal speckle correlation measurements at LCLS.
  • To analyze the impact of LCLS spectral fluctuations on single-shot speckle contrast in wide-angle X-ray scattering.
  • To propose a method for obtaining a more stable X-ray pulse.

Main Methods:

  • Simulating FEL power spectra based on LCLS operational parameters.
