Terahertz-driven linear electron acceleration
The cost, size and availability of electron accelerators are dominated by the achievable accelerating gradient. Conventional high-brightness radio-frequency accelerating structures operate with 30–50Expand

Segmented Terahertz Electron Accelerator and Manipulator (STEAM)
Acceleration and manipulation of electron bunches underlie most electron and X-ray devices used for ultrafast imaging and spectroscopy. New terahertz-driven concepts offer orders-of-magnitudeExpand

Compact electron acceleration and bunch compression in THz waveguides.
We numerically investigate the acceleration and bunch compression capabilities of 20 mJ, 0.6 THz-centered coherent terahertz pulses in optimized metallic dielectric-loaded cylindrical waveguides. InExpand

Short electron bunch generation using single-cycle ultrafast electron guns
We introduce a solution for producing ultrashort ($\sim$fs) high charge ($\sim$pC) from ultra-compact guns utilizing single-cycle THz pulses. We show that the readily available THz pulses withExpand

Terahertz-driven, all-optical electron gun
Ultrashort electron beams with a narrow energy spread, high charge, and low jitter are essential for resolving phase transitions in metals, semiconductors, and molecular crystals. These acceleratedExpand

Field-based DGTD/PIC technique for general and stable simulation of interaction between light and electron bunches
We introduce a hybrid technique based on the discontinuous Galerkin time domain (DGTD) and the particle in cell (PIC) simulation methods for the analysis of interaction between light and chargedExpand
