TL;DR: In this article, a multimode $X$-band rf pulse compression system suitable for a TeV-scale electron-positron linear collider such as the Next Linear Collider (NLC).

TL;DR: This work presents the simultaneous experimental characterization of one-photon and two- photon excitation channels in isolated CF3I molecules using ultrafast gas-phase electron diffraction and mapped out the real-space trajectories of a coherent nuclear wave packet, which bifurcates onto two potential energy surfaces when passing through a conical intersection.

TL;DR: The motion of a vibrational wave packet in isolated iodine molecules is imaged using ultrafast electron diffraction with relativistic electrons to understand and control the outcome of photoinduced chemical reactions.

TL;DR: The first experimental demonstration of the echo-enabled harmonic generation technique, which holds great promise for generation of high-power, fully coherent short-wavelength radiation, is reported.

TL;DR: A gas-phase electron diffraction experiment using megaelectronvolt electrons is reported, where the rotational wavepacket dynamics of nonadiabatically laser-aligned nitrogen molecules are captured and the angular distribution of the molecules changes from prolate to oblate (anti-aligned) in 300 fs.
