Description

We present recent results in keV level acceleration of electrons using microJoule, single-cycle THz pulses. THz-driven structures represent a promising emerging technology for development of compact acceleration of sub-femtosecond electron bunches. The millimeter scale of the driving field offers a favorable compromise between conventional accelerators which are proven & reliable but large & costly, and other advanced accelerators like plasma-based or laser-driven devices where the small accelerator structures make device control difficult and limit the charge payload. THz-driven devices benefit over plasma devices in that they are built from static, macroscopic structures that can be fabricated by conventional means but can support field gradients that are significantly higher than in conventional accelerators, promising capabilities to produce sub-femtosecond electron bunches. In addition, the strong fields in THz based devices offer unexpected versatility in the compact manipulation and diagnosis of electron bunches. Our results pave the way for development of a THz-based light source for sub-femtosecond investigation of material structure.
