The use of infrared lasers to power optical-scale lithographically fabricated particle
accelerators is a developing area of research that has garnered increasing interest in recent …

Plasma-based accelerators that impart energy gain as high as several GeV to electrons or
positrons within a few centimeters have engendered a new class of diagnostic techniques …

The terahertz gap is a region of the electromagnetic spectrum where high average and peak
power radiation sources are scarce while at the same time scientific and industrial …

We propose to use the mechanism of an echo effect previously observed in hadron
accelerators for up-frequency conversion of density modulation in an electron beam. We …

Compact, tunable, radially symmetric focusing of electrons is critical to laser-plasma
accelerator (LPA) applications. Experiments are presented demonstrating the use of a …

An analytical model for the self-modulation instability of a long relativistic proton bunch
propagating in uniform plasmas is developed. The self-modulated proton bunch resonantly …

Accelerator-based light sources such as storage rings and free-electron lasers use
relativistic electron beams to produce intense radiation over a wide spectral range for …

FACET—Facilities for Accelerator science and Experimental Test beams at SLAC—will
provide high-energy-density electron and positron beams with peak currents of roughly 20 …

The advent of chirped-pulse amplification in the 1980s and femtosecond Ti: sapphire lasers
in the 1990s enabled transformative advances in intense laser–matter interaction physics …

We report on the experimental generation of a train of subpicosecond electron bunches. The
bunch train generation is accomplished using a beam line capable of exchanging the …
