摘要

Over the past decades, advances in ultrafast technologies led to the generation of intense ultrashort THz to optical pulses with single-cycle pulse duration. Using such ultrashort pulses for electron acceleration offers advantages in terms of higher thresholds for material breakdown which opens up a promising path towards increased acceleration gradients. In this contribution, we present the first experimental demonstration of THz acceleration of electrons initially at rest. It is shown that strong-field, single-cycle THz fields accelerate electrons with peak energies of up to 0.8 keV in an ultracompact THz gun with bunch charge of 40 fC. The achieved energy spreads are as low as 5.8%.
