Data and code from: Revealing laser and electron beam evolution in 10-GeV-class laser-plasma accelerators

This dataset contains the numerical arrays and Jupyter notebooks used to generate Figures 1–6 of the associated Physical Review Research article. It combines longitudinally resolved experimental measurements of electron-beam and laser evolution with particle-in-cell simulation results for a channel-guided laser-plasma accelerator. The data include electron spectrometer images and charge-density spectra, optical spectra and laser-mode images, channel-length-dependent experimental summaries and uncertainties, and simulation results for multiple plasma-channel conditions. The included notebooks reproduce the figure-level analysis and plots using Python, NumPy, and Matplotlib. The data can be reused to compare laser and electron-beam evolution, evaluate plasma-channel guiding and down-ramp effects, or benchmark models of multi-GeV laser-plasma acceleration. No human-subject data, personal identifiers, or sensitive location data are included.
