Ultrashort electron pulse generation with single-femtosecond-level Jitter

This dataset contains the numerical and image data underlying all figures of the associated manuscript on ultrashort electron pulse generation and timing characterization. The files include experimentally measured terahertz (THz) electric field waveforms, time-dependent electron beam deflection data, retrieved electron pulse temporal profiles, arrival time drift measurements, and numerical simulation results obtained using CST and ASTRA. Numerical data are provided in CSV format with clearly labeled variables and units, and CST monitor outputs are provided as high-resolution TIFF images. The dataset enables independent visualization, quantitative reanalysis, and reproduction of the reported results. No legal, ethical, or access restrictions apply.
