Non-destructive, single-shot recording of longitudinal bunch profiles is a prerequisite for accelerator commissioning and operation. A common strategy for the measurement of ultra-short electron bunches is to sample the Coulomb field with femtosecond laser pulses. However, recording electric field evolution in single-shot with THz bandwidth is a largely open problem and has been recognized as...

Controlling optical properties with nonlinear light-matter interactions, which has been the justification of optical lasers, remains largely unexplored in the hard X-ray region. By combining nanofocusing optics and stable X-ray pulses from SACLA, we are testing various concepts of nonlinear devices to control the temporal and spectral properties of XFEL pulses. In this talk, I will discuss our...

FLASH, the free-electron laser in Hamburg, operates in the self-amplified spontaneous emission (SASE) regime, leading to a unique combination of energy, spectrum, arrival time and pulse duration. So it is critical to be able to determine the pulse duration and arrival time of each pulse. THz field-driven streaking has the potential to deliver single-shot pulse duration information basically...

63. Photon arrival time monitoring with few fs measurement uncertainty at MHz rate

Oral

Pump and probe technique with X-ray free electron lasers (XFEL) is a powerful tool to study ultrafast X-ray matter interactions and subsequent ultrafast dynamics. It requires precise characterization of X-ray temporal properties, i.e. relative X-ray arrival time with respect to external optical laser pulses, X-ray pulse duration, and structure, preferably on a shot-to-shot basis.
In this...
