Split ring resonator based THz-driven electron streak camera featuring femtosecond resolution

摘要

Through combined three-dimensional electromagnetic and particle tracking simulations we demonstrate a THz driven electron streak camera featuring a temporal resolution down to a femtosecond. The ultrafast streaking field is generated in a resonant THz sub-wavelength antenna, which is illuminated by an intense single-cycle THz pulse. Since electron bunches and THz pulses are generated by the same laser system, synchronization between the two is inherently guaranteed.
