TL;DR: In this paper, the authors reviewed the dielectric laser acceleration (DLA) scheme operating at typical laser pulse lengths of 1 to 1 ps, where the laser damage fluences correspond to peak surface electric fields in the Ω{GV}/\mathrm{m} regime.

TL;DR: The first experimental test of the physics of plasma wake-field acceleration performed at the Argonne National Laboratory Advanced Accelerator Test Facility is reported, and the results compared to theoretical predictions.

TL;DR: A new regime of single-surface multipactor was observed during high-power testing of an 11.424-GHz alumina-based dielectric-loaded accelerating structure, in which strong normal and tangential rf electric fields are present and the power flow is parallel to the surface, and more than half of the incident power can be absorbed.

TL;DR: In this article, the authors investigated a new technique for microwave detection of cosmic-ray extensive air showers which relies on detection of expected continuum radiation in the microwave range, caused by free-electron collisions with neutrals in the tenuous plasma left after the passage of the shower.
