Spectral-phase interferometry for direct electric-field reconstruction applied to seeded extreme-ultraviolet free-electron lasers

Correspond- ingly, the population with the lowest percentage of trees with serotinous cones had significantly heavier seeds that performed better under control conditions (i.e.

Using relativistic electrons an intense radiation is obtained in each bending magnet (Fig. 1) and we recall briefly the properties of this radiation. a) The spectrum of emission is

Abstract - The energy spread of field emission oriented <100> and <111> tips has been measured in the working conditions of CTEM.. The different parameters that

We introduce a new approach to the characterization of femtosecond optical pulses based on a remarkably simple setup combining a two-photon detector and a pulse shaper consisting of

The complete characterization— in both amplitude and phase— of ultrashort pulses has given rise to a great variety of experimental techniques, 1 – 3 with the advent of

Here we report the generation of two-colour extreme ultraviolet pulses of controlled wavelengths, intensity and timing by seeding of high-gain harmonic generation free-electron

• In Chapter 4, we describe a seriation algorithm for ranking a set of items given pairwise comparisons between these items. Intuitively, the algorithm assigns similar rankings to
