A compact streak camera for 150 fs time resolved measurement of bright pulses in ultrafast electron diffraction
We have developed a compact streak camera suitable for measuring the duration of highly charged
subrelativistic femtosecond electron bunches with an energy bandwidth in the order of 0.1%, as
frequently used in ultrafast electron diffraction UED experiments for the investigation of ultrafast
structural dynamics. The device operates in accumulation mode with 50 fs shot-to-shot timing jitter,
and at a 30 keV electron energy, the full width at half maximum temporal resolution is 150 fs.
Measured durations of pulses from our UED gun agree well with the predictions from the detailed
charged particle trajectory simulations
Optical fiber-driven low-energy electron gun for time-resolved streak diffraction
The wave guiding feature of the optical fibre optical fibres is specifically exploited to construct a novel type of electron gun to realize single-shot low-energy electron diffraction experiments with the sub-picosecond resolution for studying irreversible samples
