Description
We report progress on a THz streaking experiment at the UCLA Pegasus Laboratory enabling femtosecond-resolution electron bunch length measurements. Single-cycle, 50 µJ THz pulses centered at 0.6 THz are coupled into a metallic horn structure, enhancing field strengths to several hundred MV/m while simultaneously establishing boundary conditions for a strong streaking gradient. A multi-frequency RF photoinjector system produces ultralow-emittance, high-brightness electron beams, which are compressed to sub-femtosecond durations at MeV energies. This setup enables demonstration of THz streaking-based longitudinal point-spread function measurements with femtosecond resolution.
