X-ray lasers represent a powerful tool to explore matter under extreme conditions. A rigorous characterization of their output parameters is, therefore, of substantial importance for the purposes of the experiments being conducted at these sources. A

Free-electron lasers (FELs) have invigorated physics research, but novel sources require novel means of beam characterization as an integral part of any experiment. In this study, desorption imprints in plastic yield transverse intensity profiles of

Sub-femtosecond precision measurement of relative X-ray arrival time for free-electron lasers

Publikováno v: Nature Photonics
Nature Photonics, Nature Publishing Group, 2014, 8 (9), pp.706-709. ⟨10.1038/NPHOTON.2014.164⟩

Today's brightest coherent X-ray sources, X-ray free-electron lasers, produce ultrafast X-ray pulses for which full-width at half-maximum durations as short as 3 fs have been measured(1). There has been a marked increase in the popularity of such sho

Publikováno v: Physical Review Letters. 108

All matter exposed to intense femtosecond x-ray pulses from the Linac Coherent Light Source free-electron laser is strongly ionized on time scales competing with the inner-shell vacancy lifetimes. We show that for nanoscale objects the environment, i

X-ray–optical pump–probe experiments at the Linac Coherent Light Source (LCLS) have so far been limited to a time resolution of 280 fs fwhm due to timing jitter between the accelerator-based free-electron laser (FEL) and optical lasers. We have i

Publikováno v: Optics express. 19(22)

We present a new technique for measuring the relative delay between a soft x-ray FEL pulse and an optical laser that indicates a sub 25 fs RMS measurement error. An ultra-short x-ray pulse photo-ionizes a semiconductor (Si(3)N(4)) membrane and change
