TL;DR: In this article, a measure-and-sort approach was used to achieve sub-10 fs root-mean-squared (rms) error measurement at hard X-ray FELs, far beyond the 100-200 fs rms jitter limitations.
Journal ArticleDOI

TL;DR: The current technique for "measure-and-sort" at the Linac Coherent Light Source at the SLAC National Accelerator Laboratory is reviewed, placing timing precision at the same scale as the duration of the shortest achievable x-ray pulses.

TL;DR: In this paper, a single-shot measurement of the relative delay between x-ray FEL pulses and optical laser pulses has been improved to 10 fs rms error and has successfully been demonstrated for both soft and hard X-ray pulses.
